i don't see the connection. trickle down economics is about reducing taxes for high earners so that they can spend the money on things that will eventually benefit lower earners. that has nothing to do with effective altruism as far as i can tell.

at best i can see that high earners claim effective altruism for themselves, and are discrediting it with their actions, just like i said.

if you talk to people promoting effective altruism on the ground (which i had the opportunity to do recently) then you get a different picture.
