I used a german tax calculator and put in a 200k Euro income and it told me my take-home would be 102k. I dunno if I screwed it up or anything -- I don't know a lot of German tax law.
The person who set off this thread made no claim to be a typical Berlin developer, he just said that he paid 42% taxes, and someone challenged that claim. If everyone's being super careful about using very precise language, fine, but that needs to be everyone being super careful about using very precise language, not just people you disagree with.
