Rich people deserve to be rich because they work harder. Why should they give up their money?
Capitalists gain their wealth from the labor of others–not from their own work. The workers who actually create the wealth-by picking the crops or assembling the engines, for example-should get a fair share of the wealth they create. Why should someone be a millionaire, with three houses, a private plane, and the like when other folks can’t even afford enough to eat?
