Wealth taxes are inherently undemocratic and amount to illegal double taxation. They are not a reasonable subject for discussion.
They also impose a significant threat to social justice, as wealth doesn't get adjusted and eventually covers the top 50% and the top 1% is excluded anyway thanks to loopholes only they can exploit.
In order to create a fair taxation regime, first you need to link all tax caps and limits to indexes such that they automatically adjust wrt to their peers.
