We don't agree. Flat taxes inherently benefit the wealthy and exacerbate income and wealth inequality. The current world financial situation as well as the sometimes very detailed financial history of the world over the last 100 years and less detailed history of the last 2000-4000 years has shown decisively that the higher financial inequality is, the worse a society is. IMHO we (the US) are hastening our fall from top economic power in the world in large part because we have such high inequality.
