> There's very high taxation of high income individuals (60%)
55.9% *, at highest bracket. And when you get there, you usually have means to have at least some of your income as capital gains, which is uniformly taxed lower. I.e. you don't become a high income individual, you become an owner of profitable family business.
Edit: I said originally, "55.9%, marginal", but that was wrong. Corrected.
