Well, it is marxist, even if western states do it. Esping-Andersen, the modern welfare state guru is heavily influenced by the works of Marx. It doesn't matter if other western states do it too, it's still unfair.

A flat tax is the only fair tax and what people don't see is that it increases national budgets dramatically...in EVERY SINGLE COUNTRY it was introduced. If it's tiny as Estonia or huuge as Russia, national budget was increased directly by the introduction of a flat tax (as a direct outcome, controlling for any sort of other factors which may have influenced that increase). The Bush administration fought hard to introduce it. I still admire them for that. In Germany, the Christian Democrats initially campaigned on that but because it was badly received by the press, Kirchhoff, the "to-be" Finance Minister was dismissed. It's just stupid really.With more money in the federal budget, the US could run more schooling/ welfare/ infrastructure programs and they wouldn't need to further push an out-dated progressive tax model. I think the Heritage Foundation was speculating that a flat tax of 22% would already increase the Federal Budget. Bust still people go for the marxist solution. It's sad.
