From Phil Gramm and Steve McMillan in their article in the Wall Street Journal, The Real Causes of Income Inequality, 4/6/12.
Inequality is a natural result of the expansion of liberty and the development of new technology and new products. Henry Ford, Andrew Carnegie, Sam Walton and Bill Gates caused the income distribution to become more uneven, but they enriched the world.
To vilify success and the rewards it garners is an assault not just on capitalism but on liberty itself. As Will and Ariel Durant observed in “The Lessons of History” (1968), “freedom and equality are sworn and everlasting enemies, and when one prevails the other dies . . . to check the growth of inequality, liberty must be sacrificed.”
There is no victory in a class war.
