The great and chief end … of men's uniting into commonwealths, and putting themselves under government, is the preservation of their property (John Locke).
The transformation of scattered private property, arising from individual labour, into capitalist private property is, naturally, a process incomparably more protracted, violent, and difficult, than the transformation of capitalist private property, already practically resting on socialized production, into socialized property. In the former case, we had the expropriation of the mass of the people by a few usurpers; in the latter, we have the expropriation of a few usurpers by the mass of the people. (Karl Marx).
