I was listening to NPR coverage of the US Republican convention, while playing Civilization V. In a speech by Mike Huckabee he contrasted Obama's and Romney's charitable giving. In Huckabee's numbers Obama gave 2% versus Romney's 16%. Admittedly in the tax returns that Romney released showed he pay taxes at a rate of 15%. More of Obama's income is "earned" than Romney. However the idea to replace public sources of welfare with private sources of charity is a nonstarter. It has already been tried in the 18th and 19th century, read Dickens et al.
