How would the morbidly wealthy profit out of chaos?
- to greatly simplify a very complex process -
When society and economy crash, many (most?) of the "regular" people and business are forced to sell off some of their assets, and/or liquidate them completely as they "lose everything" ....
The ultra-wealthy are relatively unscathed and still have plenty of money to swoop in and "pick the bones clean" at a fraction of what assets are actually worth.
When "things return to normal" the hyper-wealthy own much more than they did before, and they got it at absurdly low prices.
And the vast majority of society has far less than it previously controlled. Plus, in the US, the billionaire class has additionally leveraged its wealth into political power as well.
