I'm doubtful of any tax-based plan as a longterm solution. Here's why. Money needs to flow in a circle for a sustainability. But we can't force people to spend all their money monthly and even then tax is not 100% so net negative monthly shortage risk. Maybe we need a spend it or lose it basic-credit system.

About high paying jobs, suppose we pay 100$/hr for people to monitor the machines, up to a cap of 1K$/mth.

Here's one of the semi startrek-esque longterm solution that works reliably but not yet possible. Suppose basic goods productivity improves 10000X. Then a small number of people can produce the basics for everyone without any money issues involved.
