You have to wait till they sell

. Elon musk sold a lot of stock and paid out the anus cause of it. If they are willing to let it sit, they aren’t enjoying that money. When they sell it you hit them with the taxes which is fair. If a wealthy person buys stock, that money used to buy it is already taxed. A person like elon musk worth billions due to his companies stock worth means nothing until he sells it. Granted, many of these people can tap into credit since banks know they can pay it back but that only buys a person time. Eventually you wanna put that money tied up in stocks to use you have to sell it.
