@Flux @scottsantens Modern Monetary Theory supposes a contrafactual, which is that the persons most necessary to tax can be taxed. (Obviously not true. The cost to buy a government is much less than the taxes; existence proofs of this abound.)
It supposes a second contrafactual that taxation is fast enough to impose a functional and sufficiently low lid on great personal wealth. We know that's not true because it was tried and failed hard across generational time.
