Taxing wealth (not income) temporarily is a useful tool to address these extraordinary imbalances in an eventually zero sum game. I'd rather have a very low flat income tax plus add on wealth tax on extreme wealth than the current status quo of high and progressive income taxes and no wealth tax.
They're using it to control politicians.
