I get that it is popular to hate billionaires these days, but realistically, they did not get to be billionaires by being stupid. It runs directly counter to their own interests to induce anything like 45% unemployment. They will get poorer, the world they live in right along with the rest of us will get noticeably shittier, etc.
More likely they figure out what to do with a bunch of idle talent. Or the coming generation of trillionaires will.
"Poorer?" That implies they still rely on money. But money is just a form of fiat power. The billionaires/trillionaires will not much need fiat currency or fiat power, because they're building real power.. by extension, they won't really need to worry very much about the rest of us, either..
