I am committed to give all that I can -- living frugally as much as reasonable until I die. I think we should be more worried about people that simply haven't come to understanding that we need to help the world, and that other lives matter as our own, than about people giving significant part of their incomes to charity. Of course, the idea is you don't have to do that -- if everyone gave 10%, the world would be much, much better![1].

Heck, sometimes (see the war in Russia), people are actively doing the opposite and trying to destroy civilization.

Btw the phrase "morally isomorphic" is a delightfully creative piece of language -- both intuitive and precise.
