I know SOME countries are ok with turning over 50% or more of their income to the government, but most Americans aren't really into that.
It's not really 50%. Taxes taken out of salary depend on how much you earn, you dont pay anything if its under £18k I think, the most anyone pays is 25% and thats the pretty wealthy. We have huge taxes on petrol and cigarettes etc. but it's a goo deterrant so it makes sense.
