The shares he owns in his company are grossly overvalued. Imagine if he owned 100% of Tesla. That happens a lot on the stock market. There's plenty of companies who are broke, make no money or insolvent but have massive market valuations because people are buying up shares like crazy which is in turn causing it to rise. That can go on as loooong as possible and even decades, as long as the bank will keep giving you credit and you at least make minimal payments.
Bruh I read somewhere that America's billionaires could give all Americans $1000 and still have more money than they did before the pandemic started. That's some crazy shit.You know what's even crazier?? We're still in recession and usually after a recession markets SURGE tremendously for consecutive years. That means that by the end of 2021, Elon Musk and Jeff Bezos might double their Current net worth. ASSUMING their company stock price doesn't take a beating.
