Tax revenue as a % of GDP. Sweden is highest.

Yes, but as someone who has lived in Sweden for 7 years, I can tell you that these taxes benefit Swedish society. Also the corporate tax rate is reasonable and you don't need to purchase private health insurance for employees. Also in general there is less litigation.

I think America should consider being a bit more above board and just increase the income/corporate tax rate. The current American taxes are mostly hidden inflation - print more money when you need it... But that game will be over soon.
