[Unsimplified]

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.

Just to be clear. You're doubtful that this will work so we shouldn't try, and should continue to watch people living and dying on the streets from the comforts of the lavish accommodations?

Then you go on to propose fantastical, never gonna happen, jobs just poofing into existence at some indeterminate date in the future? Perhaps when enough people have died on the streets as to make UBI palatable over more food and housing riots? That's where we are headed if we can't start fixing these problems there will be riots.
