A list (compiled by Forbes magazine) of the 75 richest people in all of history, going back to Crassus (No. 8) and Pharaoh Amenophis III (No. 12), shows that an astonishing 14 of them (including John D. Rockefeller and Andrew Carnegie, Nos. 1 and 2) were Americans, born mostly of humble origins between 1831 and 1840. That made them just the right age to take advantage of the tremendous creation of wealth in the years following the Civil War.
The example of those men, and those decades, has colored American attitudes toward wealth ever since. It persists today, according to Page and Jacobs, who found that "large majorities of Democrats and low-income Americans agree with Republicans and more affluent people that it is still possible to start out poor, work hard, and become rich."
