Sadly I think you're right, and that last part is the unsustainable part; I don't think any one of them considers what it means for them personally when this all hits the wall and comes to an abrupt halt. All those billions of dollars will be meaningless when the global economy shifts away from the US dollar as the reserve and you end up with trillion dollar bills like Zimbabwe. It's just economic suicide, even for the owners and CEOs, but they're so brain-rotted and coked out they can't or won't see it. If you ask me they belong in some sort of rehab program after their assets have been seized, or in jail. The amount of social harm done through jobs lost and economic devastation eclipses a thousand fold a street level murder, we need to start looking at financial crime differently.
