Capitalism benefiting the poor?

Konkin on Libertarian Strategy - Murray N. Rothbard - Mises Institute: "the emergence of wage labor was an enormous boon for many thousands of poor workers and saved them from starvation. If there is no wage labor — as there was not in most production before the Industrial Revolution — then each worker must have enough money to purchase his own capital and tools. One of the great things about the emergence of the factory system and wage labor is that poor workers did not have to purchase their own capital equipment; this could be left to the capitalists. (Thus, see F.A. Hayek's brilliant introduction in his Capitalism and the Historians.)"
