For the record, however, the most-taxed countries on Earth (i.e., the countries where revenue is the highest percent of GDP) are in order:

1. Denmark

2. Sweden

3. Belgium

4. France

5. Norway

In terms of per capita GDP these are, respectively, the 4th, 9th, 14th, 15th, and 3rd richest countries on earth while the United States is 17th.
