Doing some math, it would appear that the average American who earns the average wage of $48,463 pay taxes way below the global average. About 24.6% of the salaries go to income tax and social security. The take home pay is more than 75%.

In real life, children, marriage and different salary grade tend to be significant in its effect to income tax rates. Married workers with children, however, tend to enjoy lighter tax loads according to OECD.
