Doesn’t matter if it’s all “paper profit.”He doesn't have a Hundred Billion in the bank. It's all "paper profit". Oracle not going away but the only way you get the (profit) is to sell the stock, then pay taxes. If Oracle stock goes down so does his net worth. I'm not saying they could be destitute even really rich folks can have cash issues.
Keep in mind that rich people can borrow massive amounts of money based on the value of those “paper” assets which gives them huge financial power and resources.
This is why you should never listen to rich people who claim they are “not taking a salary.” The reality is that they are borrowing their income at very favorable interest rates and paying the loans down with increases in stock price. They play the margins.
The rules are different for the extremely wealthy.
