Of course it will, just not on a very quick (and destructive) timeline. He loses a monopoly abusing company and its excess profits which fed inflated salary and stock compensation for him personally and is instead left with taking the equivalent of the S&P 500 return or trying his hand at actually being a good manager and growing a company from small to large again or investing in early stage private stuff and experiencing the huge risk of that. If he's actually a good manager/ entrepreneur he can still grow his wealth starting something new, if he's not then he, or his kids, or his grand kids will eventually put enough of the wealth into failed company ideas, up their nose, in their veins, down their throats, into bad real estate, etc. that they cease being billionaires and have to get real jobs. This is the classic way wealth was dissipated. It's non violent, slow, but effective. most importantly it doesn't ruin the calculus on whether someone should strive to be a great entrepreneur or just keep their head down because they can be sure the government will steal it if they succeed.
