The problem with these discussions is that both sides tend to shade things to their POV. Not surprising, that's human nature.
It's true that the income tax system is progressive. There are some very good reasons for that. Primarily this is because of the declining marginal utility of income. It's also true however that the Social Security tax is regressive along with such excise taxes on gasoline, tobacco, and alcohol, as well as local (flat) state income taxes, property taxes.
When you add it all up and then add in the fact that the truly rich receive more of their "income" in different (and lower taxed ) forms that W-2 folks, it not clear that our complete tax system (state, local, federal) is as progressive as we might wish it were.
"When the snows fall and the white winds blow, the lone wolf dies but the pack survives." Winter is Coming Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die. As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
