In U.S. history books, well-known philanthropists such as Carnegie and Rockefeller are described as generous and charitable. They donated part of their great wealth to good causes such as building schools and libraries. However, what is often overlooked in this version of history is that the very basis of their philanthropy was inequality. Their fortunes were built on the backs of working people, whose labor and minimal wages allowed those at the top to accumulate large amounts of money, which they used to build mansions for themselves filled with extravagant possessions. They gave a portion of their money to good causes. Meanwhile, those who were the actual source of their wealth often could barely afford to feed themselves and their families. This scenario continues today.
