We're all under borderline subsistence, but there's a lot of us, so the total is higher. I don't know if any actual effective altes would agree with this conclusion. And i just would add that bentham, the father of utilitarianism, despaired, finally, of that challenge. He couldn't find a way to add up happiness over people, because it can't be measured.
Neuroscientist Erik Hoel talks about why he is not an "effective altruist" with EconTalk host, Russ Roberts. Hoel argues that the utilitarianism that underlies effective altruism--a movement co-founded by Will MacAskill and Peter Singer--is a poison that inevitably leads to repugnant conclusions and thereby weakens the case for the strongest claims made by effective altruists.
