First, it costs a lot (accounts and attorneys) to game the tax system. So only "the rich" can afford it. The net result is progressive taxes wind up hurting the "doing well but not rich yet". Second, if I go to a store and buy a chair the sales tax rate is flat. Everyone pays the same rate. That seems fair. But if I make a chair and sell it, the income tax I pay on the gain depends on how much income I've made that year. Thus two people making the same chair and selling it for the same gain would pay different amounts of income tax. That unequal taxing of the same gain is what is unfair about a progressive tax rate. It's much harder to split up personal income. The flat tax is not an income tax. It is a tax on the creation of wealth. Most people think a flat tax means just changes our current tax system to have just one tax rate. The Flat Tax is a complete re-architecture of what and how to tax.
