1st, don't read to deep into this, It's not even a pipe dream is a barely thought that crossed my mind but ain't smart enough to even process in any meaningful way, but thought it would be ok to vomit here.

I mean total wealth including houses, cars, personal belongings, clothes, groceries, bank accounts, shares at some company, pocket change, everything. Yes, I was thinking dollars. It could be per person. And yes, it's a VERY arbitrary number, but it could be adjusted.

It would be like a rolling cap, if you're at the limit, you could buy food, and after you eat it, that expended budget would be available for you to earn more money again.
