When it comes time to donate, don't think that you are "giving back," because you haven't taken anything in the first place. The vast majority of Americans who become wealthy have not done so by exploiting the poor. Nor have they simply lived off their family's fortune.
Two-hundred seventy-three people on the 2013 Forbes 400 list earned their wealth through businesses they started or invested in. And making all that money had many positive benefits for society. Thanks to the technology developed by Bill Gates or the inexpensive goods available to people who shop at Wal-Mart or the salaries paid by Facebook, America benefits from the contributions of wealthy individuals before they give away a dime.
