Earlier quoted context omitted.
I can't tell what's worse: intentionally obscuring the fact that the vast majority of people would pay ~no wealth tax or unintentionally forgetting that the vast majority of people would pay ~no wealth tax.
You seem to forget that given the way taxes work, eventually, anyone, with any amount of money, will be considered "wealthy" because we'll keep running out of other people's money. You're wealthy, or the definition will change to include you. The spice must flow.
that doesn't make a whole lot of sense, for two reasons. For one, as even Paul points out in the piece, a wealth tax below what's practically a risk free return on capital (~5%) doesn't eat into the capital stock, it simply means wealth grows slower, but still increases.
Secondly, there's no monotonous historical direction towards higher wealth taxes, in fact the opposite. We're living in an age of low wealth taxation, with only half a dozen countries or so, if I'm not mistaken, imposing one at all.
