The averages don't work well when you divide. You need to look to medians for the income and then compute average tax rate forthat* income.

That's true. I didn't look into how exactly Swedish rates are computed. A 25% effective rate sounded about right to me for a single-filer US salary in that range in most states which have income taxes on top of the federal+FICA. A Nordic country having 10+% higher effective rates likewise seemed reasonable but I certainly don't know for sure.
