You do know that already We have robots growing food, right?  Work We need done but no One (or not enough of Us) wants to do it, will be automated.  I'm sure there are Some who love to grow food, but likely not enough.

And given (I think I mentioned) 80% and more of Us presently just push money around, We will see plenty of Us doing the creative work, automating things, designing things, building things, teaching, practicing true medicine because They care and not because They will make bank, research into true medicine (and many other things), and on and on.

I see no flaw.

But if You can specify something You can see, let Me know.  Meanwhile I will see if I can evaluate Your suggestions.
