Why does it matter how much the shares of his company are worth? They just represent ownership of a company. It's not like their existence is somehow holding back wealth from the market or from other people. And if he wants to sell the shares to make some cash, then he's going to have to pay taxes on that, which is good for everyone else. And he wouldn't do that unless he planned to spend or invest the cash receives, which is also good for everyone else. I fail to see the harm.
