Some dude I met who was previously working in Germany told me he came to Australia because tax was too high in Germany. He told me confidently that it was 40-something percent, flat tax when you earn over a certain amount. I queried if that was the top tax bracket and he told me no. I was shocked at high the marginal tax rate was based on that.
Turns out, despite being a highly specialised metal machinist, he doesn't know shit, and Germany has tax brackets like everywhere else...
People are astoundingly uninformed.
