I personally think it's quite bad to try to get people to sign a lifetime giving pledge before they've ever had a real job, and think this is overemphasized in EA.
I think it's much better to eg make a pledge for the next 1-5 years, or the first year of your career, or something, and re-evaluate at the end of that, which I think mitigates some of your concerns
Interesting idea!
I recommend a different name, when I saw this I assumed it was about pledging around left wing causes
I feel like the spirit of the pledge would be to increase the 10% part with inflation? If you get a pay raise in line with inflation it seems silly to have to give half of that, since your real take home pay is unchanged. Even the further pledge is inflation linked
I feel pretty ok with a very mild and bounded commitment? Especially with an awareness that forcing yourself to be miserable is rarely the way to be just effective yourself. I think it's pretty valid for someone's college age self to say that impact does matter to them, and they do care about this, and don't want to totally forget about it even if it becomes inconvenient, so long as they avoid ways this is psychological even by light of those values
I guess my issue is that this all seems strictly worse than "pledge to give 10% for the first 1-2 years after graduation, and then decide whether to commit for life". Even "you commit for life, but with the option to withdraw 1-2 years after graduation", ie with the default to continue. Your arguments about not getting used to a full salary apply just as well to those imo
More broadly, I think it's bad to justify getting young people without much life experience to make a lifetime pledge, based on a controversial belief (that it should be normal to give 10%), by saying that you personally believe that belief is true. In this specific case I agree with your belief! I took the pledge (shortly after graduating I think). But there are all kinds of beliefs I disagree with that I do not want people using here. Lots of young people make choices that they regret later - I'm not saying they should be stopped from making these choices, but it's bad to encourage them. I agree with Buck, at least to the extent of saying that undergrads who've been in EA for less than a year should not be encouraged to sign a lifetime pledge.
(On a meta level, the pledge can obviously be broken if someone really regrets it, it's not legally binding. But I think arguments shouldn't rely on the pledge being breakable)
