How do you know how much money she has? What is her net worth? She's way below someone like Bill Gates (who could count $150M as disposable at .17% of his net worth), and (unless she's doing some impressive money laundering) is not a billionaire. So even if you say she has $999M, $150M is 15% of her money. Unless someone average has ~$3k to their name, $150M is a lot more to her.
