95% income is wild. But capital gains increase might not be a bad idea. Higher top brackets also probably a good idea. Taxing debt that you borrow against assets might be difficult because of mortgages. Technically I think the state gets taxes on that but only when they die. If there is a good proposal that works, I'd have no problem with it.
Just Wealth tax is not a good idea. The problem in my opinion is not that people get too rich, it's that companies get too big. We need to break those monopolies up.
