The bottom household income of the top 30% is only 65%. Even the top 10% is only $118k. If you make $200k, you are in the top 3%. $250k gets you into 1.5%.
Meanwhile the top 0.1% begins at $1.6 million, 6 times what the 1.5% make.

For those that said 30%, you are eliminating most college grads from the middle class. Only ~30% of Americans have a college degree, and less than 10% have a graduate degree. If you have a grad degree, as many here do, then you are in the Top 10% of educated Americans. That doesn't necessarily mean you are in the Top 10% income, but there is a high correlation between education and income.
