According to an old developmental narrative, agricultural employment would decline as agriculture became more productive, precipitating lots of potential new workers into towns, who would then be taken up by expanding industrial production. These developments would eventually bring every country into modernity. For orthodox Marxists, this would tendentially form a proletariat unified under the hegemony of its most “advanced” fractions in industry. But as the global peak of industrialisation recedes into history, it looks like something else is now happening. While agricultural employment has not halted its decline, those workers shed are less likely to join the ranks of the industrial working class than to enter a vast and heterogeneous service sector. At the world level, there are now twice as many workers in services as compared to industry: services account for 44 percent of global employment, while industry accounts for just 22 percent. […]
Just as agriculture comes to employ a decreasing share of the workforce, since there are limits to growth in the demand for food, so too with manufacturing: there are supposedly limits to the demand for goods (apparently, there is, however, a limitless demand for services). The result, according to this perspective, is that over time, a rising demand for services will dynamically pull workers into the service sector, just as in an earlier phase workers were pulled into the industrial sector.
In reality, the dynamic draw of manufacturing during industrialisation was unique to that sector. To manufacture something is to take a good — or to transform a service, such as dishwashing, into a good, such as a dishwasher — and to produce that good in a factory, according to ever-more efficient techniques. It is the resulting rise in the efficiency of production within the space of the factory that rapidly lowers costs of production in manufacturing lines. That leads, in turn, to a rapid fall in relative prices. Markets for manufactures expand, making possible a dramatic expansion of output. Concomitantly, huge masses of humanity are pulled into work in manufacturing lines. That is the key to the dynamic growth of manufacturing output and employment: the former is very rapid, and that is why, in spite of high rates of labour productivity growth, the latter expands, raising the manufacturing employment share.
The same does not take place in the service sector. Services are precisely the sorts of activities that cannot be — or have not yet been — substituted by goods. In services, labour productivity tends to increase slowly if at all, and concomitantly, prices follow the same trajectory. In fact, as long as real wages are rising, the relative price of services will itself tend to increase. Since relative prices do not fall dramatically, there is no impetus for markets for services to expand rapidly. Hence, there is no dynamic tendency to dramatically expand output and thus to draw lots of labour into the sector; instead, employment in the service sector expands slowly.
[…] The shift from industrialisation to deindustrialisation is necessarily the shift from an economy that grows rapidly, with big booms and busts, to one that grows slowly, tending towards stagnation. In such a context, booms and busts are given merely by financial bubbles being blown up and deflated around the world by surplus capital.
There is a corollary to this theory, which explains why a large portion of the surplus population ends up in the service sector, particularly in the low-wage, super-exploited section and in the informal, self-exploiting section. As service work tends to be labour-intensive, a large proportion of the final costs are made up of wages. Because real wages do not usually fall across the economy, it is difficult for service sector firms to lower their costs on a regular basis (general tendencies towards falling costs in industry and agriculture are due to increases in the efficient use of more expensive labour). This results in a relatively low level of output growth in services. But precisely for that reason, when workers are expelled from other sectors, it is possible to get much cheaper workers into services — as those discarded as surplus will usually have to accept a lower wage level. This lowers costs and allows for some expansion in demand for, and output of, services. In the service sector, there is greater room to expand the market by lowering wages. By contrast, in most manufacturing activities, wages make up only a small portion of the final cost of the product, so there is less room for manoeuvre.
[…]
While it is difficult to identify a precise and determinate “logic” as to why some activities become really subsumed and others do not, the fact that certain activities require delicate work or direct human contact, and therefore must remain labour-intensive, is clearly key. There appears always to be a remainder of such activities, an assortment of differentiated tasks, mostly in services. Insofar as services remain services, they tend predominantly to be a source only of “absolute”, and not “relative” surplus value. This is simply another way of saying that there are limits to raising productivity. Consequently, economies that are “post-industrial” and concentrated around service work tend to be low-growth.
In such conditions, it is imperative for capitalists to get as much out of their workers as possible, by increasing the duration or intensity of labour. To some extent, the prerequisite for the existence of many jobs becomes pressurised work conditions. If super-exploited sectors take up a growing share of the labour market, this also puts downward pressure on all wages, and increases insecurity, as workers lose bargaining power and bosses are emboldened to demand ever more flexibility. With this, the door is opened for a whole range of abuses to be unleashed upon the worker — sexual, emotional and psychological, as well as the stealing or retention of wages and chronic overworking. Certain positions, such as that of the low-wage service sector worker, thus appear as a kind of special category of surplus worker, akin to the informally self-employed in low-income countries (and in high income countries over the past decade or so). Low-wage service workers must become extreme self-exploiters, as well as being super-exploited, if they are to get work. Many of these jobs (deliveries, house-cleaning, supermarket baggers, and so on) can only exist because the wages of the people performing the service are a fraction of what those consuming the service are paid. Thus, the condition for finding a job in a growing service sector is often accepting a significantly lower than average wage.

Far from representing the emergence of a coherent agent, the expansion of the surplus population marks the tendential disappearance of the previous revolutionary horizon.
It was once possible — indeed quite reasonable — to think of the proletariat as an emergent social subject, becoming ever larger and more unified with the global spread and development of the capitalist mode of production, and particularly with the incorporation of a growing portion of the class into industrial employment. Today, in an era of slowing economic growth — which is also an era of general deindustrialisation — the revolutionary orientations of the past no longer make sense. The working class — always internally differentiated — displays a diminishing capacity for unification under a single hegemonic figure, thus realising its always latent tendency to decompose into fragments, facing off one against the other.
At the heart of this fractiousness is the division of the class into two parts: (1) a shrinking one that retains higher wages and social protections, but must constantly fight rearguard actions against capitalist “reforms” and restructurings; and (2) a growing one that faces poor prospects of employment and is offered few social protections. The more secure sector — which is also more organised — often needs the support of the more precarious in order to win its struggles. However, calls for greater “inclusion” of such people may stoke valid fears that this will undermine more secure positions, opening up access to education and training, and thereby increasing labour supply and reducing bargaining power. At the same time, members of the more precarious part may be rightly suspicious of the motives of the more secure: after the sacrifices have been made, won’t it be merely the latter’s rearguard battles that have been won? After all, those with security rarely take to the streets when it is the less fortunate who are getting screwed. The expansion of the surplus population is important in explaining this division, but it is not the only meaningful one within the class.
There is a potentially infinite variety of such distinctions, so the question of explaining current divisions can in a sense be reversed: What was the unity that is now in advanced stages of decay? How did it come about? This is a question that we have attempted to answer elsewhere in this issue, in ‘A History of Separation’. For our purposes here though, it is enough to note simply that there was once a hegemonic identity and orientation among workers that could provide grounds for affirming certain struggles as central, while excluding others as secondary or unimportant. It is equally clear that this affirmation seems less and less plausible today. In place of the identity of the worker, we are now faced with so many competing alternatives, each with its own strategic priorities: those who want more jobs against those who want to stave off environmental catastrophe; those who want to preserve the family wage for unionised male workers against those who want gender equality; those of dominant national or racial identities against those of racialised minorities, and so on.
In this sense, the fractiousness of “identity politics” is symptomatic of an era. In a period of increasingly slow economic growth under the threat of ecological catastrophe, it seems diminishingly plausible to claim that fighting the battles of one part of the class will advance the class as a whole. This is why we reject any attempt to find in surplus populations an ersatz social subject that might replace the hegemonic role played by the white male factory worker in the workers’ movement. At present there seems to be no class fraction — whether “the most strategically placed” or “the most oppressed” — whose struggles express a general interest. At the same time, attempts to conjure up a new unity from this diversity by simply renaming it as “multitude” or “precariat”, for example, merely gloss over this fundamental problem of internal division.
If there is any revolutionary potential at present, it seems that it stands to be actualised not in the struggle of any particular class fraction, but rather, in those moments when diverse fractions are drawn together in struggle in spite of their mutual suspicions; despite the lack of a stable, consistent hegemonic pole. In such moments, the demands of various sections of the class come into conflict with one another — a conflict that may bring the prospect of destabilising or undermining mutually exclusive demands and identities. The modes by which social life is organised and segmented within capitalist societies can then come to appear as obstacles to further struggle, dividing workers against one another. The question of how to move forward is then at least raised, though with no easy answers. After all, a definitive answer would involve an overcoming of the unity-in-separation that organises social life.

Marx defines the surplus population as workers without regular access to work: a worker “belongs to” the surplus population “when he is only partially employed or wholly unemployed”. [Marx, Capital, vol. 1 (MECW 35) pp. 634-635.] Marx refers to this surplus population as a “relative surplus population”, because these workers are not absolutely surplus, as in a Malthusian account (which is to say, it is not a matter of there not being enough food, water, shelter, etc). Instead, these workers are surplus relative to the needs of capital — that is, relative to capital’s demand for labour.
In the history of capitalist societies, large masses of people have been absorbed into the labour market and have come to depend entirely upon earning wages in order to survive. They cannot leave the labour market unless they can get other workers to support them. In other words, workers have to work regardless of what sort and how much work is available. They are at the mercy of capital’s demand for labour. When that demand falls and there isn’t enough work to go around, workers do not stop working altogether — unless they really have no options, in which case they become paupers. Instead, they enter one or another branch of an extensive and variegated surplus population.

Marx thought that the problem of the surplus population — ultimately a problem of the growing oversupply of, and under-demand for, labour — would intensify over time and, as a result, people would increasingly find themselves disconnected from labour markets, and hence from regular access to the wage. Indeed, Marx describes this as the “absolute general law of capitalist accumulation”. What happens is that capital’s ongoing accumulation process leads to rising labour productivity, which in turn expands the “industrial reserve army”, causing the “consolidated surplus population” — “whose misery is in inverse ratio to the amount of torture it has to undergo in the form of labour” — to grow, and increasing “official pauperism”; that is, those who cannot make enough in wages to survive, and so must beg for their bread.5 The overall result is that the accumulation of wealth occurs alongside an accumulation of poverty.
In Marx’s account, the main reason capitalist development leads to the growth of the surplus population has to do with what we have called “technological ratcheting”.6 In essence, Marx argues that the demand for labour in each industry eventually falls as labour productivity rises. New industries do come on line, at a faster or slower pace, increasing the demand for labour. However, these new industries never start out from zero: they do not need to reinvent e.g. steam power, the assembly line, the electric motor. Instead, new lines absorb technological innovations that preceded them. As a result, the emergence of new industries is less and less effective in increasing the demand for labour. Hence capital has what Marx terms a “rising organic composition”. Marx argues that it is the older lines, which have not yet been technically renewed, which tend to absorb the most labour.

[…] today, what renders many workers surplus to the requirements of capital is a dual tendency: on the one hand, towards overaccumulation — which reduces profit rates and hence slows the expansion of output — and on the other hand, towards the ongoing growth of labour productivity, which arises out of capitalist competition and results in a loss of jobs in those economic sectors where output does not increase at a rate equal to productivity. The combination of these factors ensures that, in an economy wracked by overaccumulation, the demand for labour will fail to keep up with its supply. That, in turn, will expand the surplus population.

[…] the tendency towards increasing superfluity is not a tendency towards a literal extrusion of a part of the working class from the economy. Surplus workers still need to buy at least some of what they need to survive, and therefore they must earn or acquire money in order to live. Those who are produced as surplus to the needs of capital may still receive wages in super-exploited sectors, or they may be informally self-employed and thus self-exploiting (since they lack access to capital).
[…]
It would thus be a mistake to identify surplus populations with “the unemployed”. This category is, to some extent, an artifact of 20th century high-income countries’ provision of unemployment insurance. In the 19th century, as in most low-income countries today, “being unemployed” in this sense was simply not an option. Unemployment insurance did not exist — and today covers few workers in low-income countries — so workers could not afford to be without work for long: they needed to find employment as soon as possible, regardless of the degree to which their labour was demanded by capital. If there was no demand, they needed to set up shop for themselves, without any employer — by picking through rags, for example.

Additionally, in the global economy — in which mobile flows of surplus capital discipline states — high-income states must do everything they can to prevent outright unemployment, and thus unemployment provisions, from growing too dramatically. Welfare expenditures, which are ultimately funded from tax receipts, must be kept to a minimum to avoid worrying bondholders and taxpayers. Current UK government policy, for example, is to try to eradicate, as far as possible, possibilities for unemployment as any kind of stable category, transforming welfare into workfare. As a result, in the high-income countries, many workers fall in and out of relative superfluity during their lifetime, due both to the increasing flexibilisation of the labour market and its destabilisation of categories of employment at a structural level, as well as the falling demand for labour.

On the one hand, this relatively simple theory of the tendential production of surplus population can help greatly in explaining various key aspects of the present global situation. It gives us a basis for explaining deindustrialisation, the relative growth of services, the spread of forms of insecure and flexible labour, and the numerous abuses for which this opens the way. In turn, these tendencies intensify and exacerbate the difficulty of unifying the working class under the hegemony of the industrial worker, in the way traditional Marxism anticipated; it thus gives us a basis for explaining the crisis of the left and present strategic predicaments. It also seems to offer an explanation for declining growth rates over recent decades, as relative surplus value-producing labour has become a diminishing share of global labour. […]
On the other hand […] What seems to be a standard misinterpretation or over-extension of the theory of surplus population is characterised by a hypostatisation of “the surplus population” as a singular social subject, with the apparent implication that this may be viewed as the new revolutionary agent, or at least that it is the agent behind various forms of contemporary struggle. This involves a conceptual slippage between general tendency and particular sociological or empirical cases. While it would of course ultimately be false to separate the two, it is also important not to identify them too immediately or simplistically. Thus, the theory of surplus population does not involve some kind of neo-Bakuninite romanticisation of a surplus subject “more radical” or “more dangerous” than the organised working class; nor does it involve a reading of present struggles as those of some “surplus” subject.

It is amongst these pressurised sections of the working class — the more insecure, informal, racialised stratum, which struggled to be reabsorbed by the labour market — that the riot became particularly prominent as a mode of struggle, from the mid to late 1970s, and it seems reasonable to hypothesise that this newfound prominence is directly related to the absence of possibilities for “normal”, regulatory, demands-making of the corporatist type. In developments dialectically entwined with the struggles of this section of the working class, the police in this period increasingly developed new tactics of repression specifically targeted at poor urban neighbourhoods. One might even say that the riot and its repression became a sort of proxy way in which class relations were regulated, in the absence of the “normal” mode of regulation exercised by wage bargaining, etc. This is not a perverse point: historically riots have pushed demands towards which the state has made concessions. This proved true of 2011 just as it did of 1981; more recently it has proved true in the US, after the 2014 Ferguson riots.
In Endnotes 3 we termed the social logic of stigmatisation associated with such developments “abjection” — a concept borrowed from Imogen Tyler’s recent book Revolting Subjects. With its in some ways dubious provenance, we were not especially fond of this term, but it seemed nonetheless quite appropriate as a name for certain problematics with which we were grappling. What was useful was that this term named a particular kind of abstract structure in which something is cast off, marked as contingent or lowly, without actually being exteriorised. The relevance of such a structure here should be obvious: the initially racialised communities subject to the forms of oppression that develop through this period are socially marked as a problem — or even as a sort of rejection from the healthy core of the body politic — without being literally exteriorised in any sense from either economy or state. Police repression looms large in the immediate experience of abjection in this sense, but the term is also intended to capture broader social processes, such as the moral crusades of reactionary press, or the constant obsessing of politicians over the various failed subjects of the nation. These are not simply unconnected moments; concrete connections between all of them could be articulated such that we see a particular socio-political pattern of oppression.
[…]
If the development of new styles of policing might be partially linked to the management of a surplus population at the outset then, this tie becomes increasingly tenuous as we get into the 1980s and 90s. One might speak of a developing “autonomisation” of the apparatus of repression and its related stigmatising and racialising logics. By this we mean that an apparatus which initially seems to apply in particular to clear, economically marginal, parts of the class, becomes dissociated from that strict function. While those who are subject to these processes of abjection come to symbolise the limits of affirmable class, these limits are in actuality unstable, shifting and ill-defined. They become more a socio-political, or perhaps socio-cultural, than a political-economic construct. If this is the case, it is doubtful whether we are likely to have any luck constructing the object of this apparatus in purely political-economic terms. Who is “abjected” then? We might provisionally reply, somewhat tautologically: those who are defined as such by the fact that they are the object of these processes of repression. There is no particular pre-existing trait or social categorisation which must, in itself, necessarily or inevitably mark one out as an object of these processes, which is not to say that certain social categories do not end up being reproduced in such positions. Abjection is closely related — though not identical — to racialisation.
[…]
If we are now speaking of the subjects of “abjection” rather than “surplus population” here, how about the abject as a social subject? These developments signify, however, not the creation of a new form of social (or potentially, revolutionary) subject, but rather the problem of any class subject at all. In itself, that which is abjected would seem to be by definition unaffirmable, ununifiable, for it is not a positive existence of its own, but merely the negative of something else. Those who are abjected are not something other than the proletariat. More often than not they are workers, students etc. Only, they are workers, students etc who are vilified, cast beyond the pale of social respectability. These developments represent problems for the constitution of a unified class subject; indeed, they are direct expressions of the decomposition of the class. The abject is projected as a sort of limit-concept of affirmable social class, in an operation where that class is itself negatively defined against what has been abjected. “We are not like them” replaces “the workers united will never be defeated”. And as such, abjection can have a somewhat fractal quality: not applying uniformly to one social group, but across and between social groups, depending to some extent on where one stands in the social landscape. There is always someone more abject than you.

It seems that the Endnotes group admits that there is no strict politico-economic category for a unified working class subject (corresponding to surplus population). And Laclau and Mouffe’stegory constructed in the socio-political or (at least partially) discursive field. Laclau and Mouffe’s theory of hegemony could be useful here.
