the movement of wealth from labor to capital has no relation whatsoever with arguments for or against capitalism. wealth is artificially transferred from labor to capital when the money becomes a currency, then the currency becomes debased. this is done because governments increase in size and cannot pay their expenditures. this is in fact, not a problem with voluntary trade and instead the state. so, as there's more units of currency, the pre-existing objects of capital will out scale the culturally pre-existing pay for modes of work (whether it be actual physical labor or service labor).  in short, this problem exists (devalued labor) because it's the stated goal of the central bank (federal reserve) to illegally confiscate wealth (inflation) by a set amount each year, in which they diligently accomplish. the irony is, the men at the top of these systems promote ideologies like the one you said in your post to keep you as a good little ignorant cocksleeve slave to protect themselves, because it, 1) nullifies you from truly solving the problem, and, 2) actually ensnares you and future generations into deeper bondage.
