>Becoming rich and then helping millions of people with your means is more impactful than being poor and helping dozens.

It's also more self-serving for the better part of it (as your focus is to become rich), and might never reach the second part (actually becoming rich and helping others).

It's also bogus: not many can become rich, both for reasons for circumstance making from much harder to nigh impossible for billions, and also for purely logical reasons: wealth is relative, and if much bigger numbers of people were rich, it would get lost to inflation.

So this effectively gives a pie-in-the-sky idea for what to become and when to help, to most people, as opposed to encouraging them to help dozens (or just a few) here and now.
