Ah, I did wonder how state level taxes were being accounted for, seems like the answer is they aren't. I guess I could have looked that up before posting. The values here[0] are markedly different. It shows Germany at 45%, France at 51.53%, US at 29.21% and Denmark at 50%. So I was way off the mark there, although I did think something seemed very off with those numbers. France is the 10th highest in the world, with many of the countries above it being tiny island countries or countries with vast oil reveres relative to their size like Norway and Kuwait. With this being the case, it does seem hard to imagine that more taxes will fix everything.
