Or to take an intermediate value, $10 million is 500k a year and most people will find it difficult to spend that much on themselves, so it’s going to grow on its own and compound. It will grow more rapidly if some is invested in the stock market.

Also, donating appreciated stock avoids taxes. This donation may have come out of a donor-advised fund.

Rich people can make substantial charitable donations rather easily and make a big difference. I suggest we encourage them.
