Tax Fact:  Only 4 developed countries collect less in tax revenue as a percentage of GDP than the United States:  Mexico, Chile, South Korea, and Turkey.  In other words, if you think taxes are too high in the United States, you can move to Mexico, Chile, South Korea, or Turkey and you’ll pay less, everywhere else you’ll pay more.
