“The time component of economic production became vital in Hayek’s work in economic theory. Essentially, his economic work could be said to rest on the idea that the price system is a method for coordinating economic activity through time.”

The Abolition of Work (1985)
Context: I am not playing definitional games with anybody. When I say I want to abolish work, I mean just what I say, but I want to say what I mean by defining my terms in non-idiosyncratic ways. My minimun definition of work is forced labor, that is, compulsory production. Both elements are essential. Work is production enforced by economic or political means, by the carrot or the stick. (The carrot is just the stick by other means.) But not all creation is work. Work is never done for its own sake, it's done on account of some product or output that the worker (or, more often, somebody else) gets out of it. This is what work necessarily is. To define it is to despise it. But work is usually even worse than its definition decrees. The dynamic of domination intrinsic to work tends over time toward elaboration. In advanced work-riddled societies, including all industrial societies whether capitalist or "communist," work invariably acquires other attributes which accentuate its obnoxiousness.
Usually—and this is even more true in "communist" than capitalist countries, where the state is almost the only employer and everyone is an employee — work is employment, i. e., wage-labor, which means selling yourself on the installment plan. Thus 95% of Americans who work, work for somebody (or something) else. In the USSR or Cuba or Yugoslavia or Nicaragua or any other alternative model which might be adduced, the corresponding figure approaches 100%. Only the embattled Third World peasant bastions — Mexico, India, Brazil, Turkey — temporarily shelter significant concentrations of agriculturists who perpetuate the traditional arrangement of most laborers in the last several millennia, the payment of taxes (ransom) to the state or rent to parasitic landlords in return for being otherwise left alone. Even this raw deal is beginning to look good. All industrial (and office) workers are employees and under the sort of surveillance which ensures servility.

1970s and later
Context: Keynesian economics was, in the context of those times, essentially conservative. The message was that capitalism was not doomed; its major failing, chronic large-scale unemployment, could be remedied fairly easily, by intelligent use of the fiscal and monetary instruments governments already had at their disposal. This message was not welcome news to Marxists committed to the view that the system was no longer structurally capable of prosperity and progress.

The Marxian approach to system theorizing clearly points us to sociologically important phenomena: the material conditions of social life, stratification and social class, conflict, the reproduction as well as transformation of capitalist systems, the conditions that affect group mobilization and political power, and the ways ideas functions as ideologies.
