Yes, but more specifically, it's 20% on top of your marginal rate on your capital income which maxes out at 20% federal in the U.S. for long term gains However, it is much closer to 0% for the most wealthy Americans because they never realize their gains, which is the only time the U.S. taxes capital gains. They just fund their lifestyles with debt against their assets. Then when they die, their heirs get a basis step up at death.

Graham gets this totally wrong, adding the 20% to 37%+4.75%, which are rates applicable to labor income (and short term capital gains, but those are very rare among the most wealthy Americans). That is such a major error it is hard to take any of the argument seriously.

Edit: Updated account for short term gains.
