America's abundance was created not by public sacrifices to the common good, but by the productive genius of free men who pursued their own personal interests and the making of their own private fortunes. They did not starve the people to pay for America's industrialization. They gave the people better jobs, higher wages, and cheaper goods with every new machine they invented, with every scientific discovery or technological advance- and thus the whole country was moving forward and profiting, not suffering, every step of the way.
