Read my comment - it is completely irrelevant to the discussion being had about the linked article, and no one on the planet is suggesting a 20% wealth tax. That is my point.

The argument was that it was ludicrous to say a wealth tax of x percent > income tax of x percent in actual impact, yes?

It is clearly the case if you try to apply the income tax rate as a wealth tax using concrete real world examples.

Even a 3% property tax makes it very difficult for many normal people to own those assets in many real world economic circumstances.
