The effective total tax rate for Americans varies, too: "The top 1 percent of American taxpayers still pay an effective tax rate of approximately 31.9 percent, on average, while the bottom 20 percent of the population pays an average of approximately 3.9 percent," reports the Peter G. Peterson Foundation.

First of all, Pete Peterson is a guy who has been trying to eliminate social security his whole life. Secondly, that figure of 3.9% can't possibly be true, if you include payroll taxes like ssdi, medicare, unemployment insurance, etc. Most Americans pay about 17-20% total tax including their payroll taxes, no matter what bracket they are in, and anyone in the top 1 percent who is paying an effective tax rate of 32% should fire their accountant.
