Linear progression is unfair, just like for taxation. If you're going to make a law like this, it should be something like nlog(n) so that the big players that abuse the system pay more than the little guy.

Now you made me wish for nlog(n) income tax as well.

n*ln(n) - a, such that below a, people receive a negative tax/progressive UBI.

We used to have something similar in France: solidarity tax on fortune (ISF), abolished by Macron at the height of the gilets jaunes movement in a big "fuck you" move.

Now it's much easier for wealthy elites to not pay taxes at all, as outlined in the past year with the Zucman tax debates (which elites opposed for daring to propose a 2% floor tax rate for those who don't pay 2%), and lately with the ministry of Finance Amélie de Montchalin lying to the members of parliament about the existence of a note produced by her own ministry showing that over 13000 millionaires pay effectively 0% income tax.
