You're not going to starve in America if you lose all your money.
Besides, Elon's dad at one point invested in Elon's company. Elon was already a success in business by then. From $20,000, he became the richest man in the world. All by luck! Pretty amazing!
Me, I could scrape up $20,000. Could I turn it into the richest man in the world? Nope. I would never have taken the risks Musk did. Nor do I have his work ethic. Nor am I as smart as he is. So I'm not envious of him.
