Our council tax in the UK, which would be the equivalent to SimCity town tax, is somewhere about 3-5%. It is actually a regressive tax, fixed based on almost made-up property prices, but you seem to be confusing national taxes with local taxes.

Although some of the national tax goes back to the councils and some of the national taxes pay for the infrastructure, so it's a bit more complicated than that.

Really? What is it?

I live in one of the high-tax places, earn well above average and do no tax planning. Yet, what the taxman actually charges me is only half the nominal maximum.
