Earning to Give as Costly Signalling

There’s a background belief that informs a lot of my Effective Altruism thinking, that might be a good time to challenge:

I think most of the value of most earning-to-give is primarily a sort of costly signaling to attract the attention of the extremely rich (who completely dwarf the funding capabilities of the bulk of EA donors), *or* in donating to places that are for various reasons can use smaller amounts of startup money. (Either you have good reason to think they’re useful that the current super-rich don’t, funding smaller scale experiments, etc)

(This comes with the caveat that, say, getting Elon Musk’s attention isn’t obviously net positive because he may or may not have actually understood what Superintelligence was warning about)

This doesn’t mean that earning to give isn’t important, but it changes a bit about what sorts of earning to give are most important and why.

The main argument I’ve seen that points in a different direction is the notion that having all of your funding come from a few super-rich people makes you much more beholden to them, which can warp your choices. I think even in light of this I still believe the above, but maybe I should weight it differently.

This has informed how I participated in a few different discussions, but I haven’t had a discussion directly examining this belief. I’m curious about people’s thoughts.
