Don't most wealth taxes that have been proposed have a certain level of wealth that you pay no taxes on? If so, doesn't that make this at least partially incorrect?
Maybe I'm missing something, but if I have $100 and have to pay a 1% wealth tax on it then sure that's roughly 20%. If I have $100, but I only have to pay a 1% wealth tax on everything over $90 that's more like a 2% income tax.
