Below this level of consumption, they’ll prefer consuming dollars to donating them, and so they will always consume them. And above it, they’ll prefer donating dollars to consuming them, and so will always donate them. And this is why the GWWC pledge asks you to input the C such that dF(C)/d(C) is 1, and you pledge to donate everything above it and nothing below it.
Wait the standard GWWC pledge is a 10% of your income, presumably based on cultural norms like tithing which in themselves might reflect an implicit understanding that (if we assume log utility) a constant fraction of consumption is equallycostly to any individual, so made for coordination rather than single-player reasons.
Yeah but this pledge is kind of weird for an altruist to actually follow, instead of donating more above the 10%. (Unless you think that almost everyone believes that most of the reason for them to do the GWWC pledge is to enforce the norm, and this causes them to donate 10%, which is more than they’d otherwise donate.)

I thought you were making an empirical claim with the quoted sentence, not a normative claim.
Ah, fair.
