This is a good point, well articulated and I agree with you.
When I say “it has nothing to do with responsibility” I’m thinking of what motivates the USA to provide this aid. Maybe I’m a cynic but I don’t believe they would ever spend money in a foreign nation simply because it’s the responsible thing to do.
But yeah, they are responsible for multiple reasons, as the ladder analogy explains, and as another commenter mentioned, for the part the USA and other privileged nations have played in creating the problems these aid programs are addressing, through colonialism and climate change. The USA specifically also did immeasurable damage to this part of the world going to war with Vietnam, Laos and Cambodia.
I’m not sure we should put much faith in these scores.
I see Canada looking pretty yellow here, but we just had a provincial government call an early election and send out $200 bribe cheques. Sure they don’t call it a bribe, but I haven’t gotten a paper cheque from the government in years (direct deposit, yay) and now I have a paper cheque and a voter card showing up in my mailbox just days apart. It’s getting pretty obvious over here.
