The problem with that is that with the current corporate oligarchs there will be pushes for structuring in policy to make sure only they and their circle can vote. Suddenly you would see a bunch of legislation calling for multiple "stimulus " payments that magically target and match average regional tax payments for certain voting demographics.

I agree with it as a test, but it can't be the only one. I think a "are you or have you been on public assistance for more than 6 months in the past 3 years " question as well as a constituonal test would work, i.e. "The 2nd amendment was written to give civilians the right to keep and bear arms: True or False" You say false, fuck off to the congo.
