This is what drives me up the wall whenever Bill Gates comes up. His net worth is double what it was a decade ago. He's not doing philanthropy, he's doing investing.
I mean... The two are not necessarily mutually exclusive. If Bill Gates gives away 49% of the money his investments make a year (hypothetically), he makes money, and he gives money away. If he funds the Series A of a biotech company to help it continue its research and the company then gains value, it's not just investing, it's also philanthropy.
He has also pledged to give 95% of his wealth to charity, so most of that net worth increase should end up going to charity eventually.
After he is dead? Does it mean it is moral to kill him ASAP?
Anyone who has invested broadly in the stock market should have more than doubled their wealth from a decade ago
