If I understand what you're saying it's that as rich as they are, the amount of money the ultra-wealthy own just doesn't add up to nearly enough to give everyone a quality of life that they deserve / once had?

Perhaps what's happening is that in their attempts to reach a personal all-time high in their bank accounts the ultra-wealthy are destroying value and economic systems en mass with little regard to the efficiency of their money siphoning process?

It's kind of like a drug dealer selling brain burning addictive substances to a few people on a street. Sure they're going to extract a person's life savings to date and whatever money that person can steal once they're addicted but that value pales in comparison to what that person could have made over their career, what it could have made if properly invested, the cost of law enforcement to deal with these addicts, the cost of the stuff that they destroy in their quest to get money to buy drugs, the opportunity cost of them not raising their kids to be productive members of society... like it all just snow balls all so some asshole can make a few bucks...

The ultra-wealthy are doing that shit where people burn acres of pristine forests to get some biochar -- but to the entire world.

  Isn’t it strange
  That princes and kings,
  And clowns that caper
  In sawdust rings,
  And common people
  Like you and me
  Are builders for eternity?

  Each is given a bag of tools,
  A shapeless mass,
  A book of rules;
  And each must make-
  Ere life is flown-
  A stumbling block
  Or a stepping stone.

What is a stumbling block? Who are they made for?

Turns out it's a fictional object created in the translation of the Koine Greek for "obstacle".
