In doing so, you're betting that _you_ can grow your money faster than organizations you give it to can make impact on their communities.
Helping people who need it _now_ rather than in ten years helps _them_ start contributing more effectively to their communities, or blunts negative effects of them _not_ having that help for the next ten years.
Sure, it's a bet you can make that you'll grow your money faster than it would have impact being put into the world --- but it's one that takes a certain amount of hubris.
Would be interesting to model this out, time value of money, time, etc.
What does it look like for someone fresh out of college to dive into making an impact vs waiting till they're 50, a billionaire? Use climate as an example, assume the problem is getting worse at 10% a year. With climate especially there are tipping points too, i.e. maybe there's a cliff at year 49 where it gets 200% worse.
What kind of challenges lend themselves to "get rich then give"? What kind of challenges lend themselves to "dive right in"?
