Re ideology. Its an choice between 2 similar taxes. And there are many, many reasons for structuring taxes.
Re captial gains tax.
Over the very long term, you would expect your investments to at least track inflation, and you would expect to sell of those investments to buy things. Its not clear to me that these 2 taxes necessarily end up very different. Should we not expect to get at least a flavour of what to expect by looking at capital gains tax?
I am curious to see the comparison as well. I suppose one difference is that capital gain tax can be delayed far into the future. Wealth tax could also have a cooling effect on stock market bubbles.
