he dosent have 40 billion in wealth. its 40 billion of paper profits (supposed profits). if he brought everything to the market to sell it would be much much less thatn 40 billion
I don't know what your point is. His shares in Berkshire alone are worth $37,217,098,141 using todays share price. Doesn't take into account personal fortune accumulated over the years. Course it is paper wealth. Name me a billionaire whose wealth isn't. I don't see how that proves your theory that he can't survive in this current market or has made alot of wrong decisions
