> To convert between wealth and income tax rates, you have to divide by the rate of return on capital. The conversion rate of 20 comes from assuming that the risk-free rate of return is 5%.
This seems to only be true for people whose income entirely comes from their wealth, rather than their labor. The math doesn't math for someone on the other extreme end of the spectrum who has zero savings or investments and obtains all his income from labor: To him, a N% wealth tax = 0% income tax for all N. Those with -some- savings are somewhere in the middle.
It is a very sneaky way to argue that a wealth tax should be as across-the-board unpopular as a large income tax increase. But Graham's math is only applicable to those flush with investments and with relatively small salaries from labor, so a wealth tax is only unpopular to that particular group.
