The extractive power it affords derives from the social relations between people with property rights over (and, therefore, autonomous access to) means of production (capitalists, landlords) and the rest. The asymmetry in capital ownership leaves those who do not own capital no alternative but to sell to capitalists their commodity labour (see 1.2.2), for a wage, and, in the process, to generate surplus value (see 1.4) for the capitalists.
