  Among the major casualties of Olson’s revision of our views of groups is Karl Marx’s analysis of class conflict. Although many scholars still elaborate and defend Marx’s vision, others now reject it as failing to recognize the contrary incentives that members of the working class face. (Oddly, Marx himself arguably saw the cross-cutting—individual vs. group—incentives of capitalists, the other major group in his account.) This problem had long been recognized in the thesis of the embourgeoisement of the working class: Once workers prosper enough to buy homes and to benefit in other ways from the current level of economic development, they may have so much to lose from revolutionary class action that they cease to be potential revolutionaries.
