But what’s the difference between $10M and $500M? In both cases, you can stop working for a living and do whatever you want with your life instead.
You couldn't start Social Capital on $10M, for example.
Sure, if you have a bunch of money and throw that money at things, you'll "change the world", but that doesn't mean that's an effective way of making lasting or useful change.
But the Gates Foundation doesn't run on $10k. You can found zero biotech companies on $10k. Money, alas, has value, believe it or not.
