This is why so many people find EA annoying. People donated to malaria causes well before EA was a thing, but of course now, without EA, there's nothing.
All the mainstream political suggestions for taxation/wealth distribution focus on correcting wealth inequalities within a rich nation. Very few (if any) suggest redistributing from wealthy western nations to the global poor.
Obviously AMF has been around before EA, the big difference is the additional amount of money it’s been able to deploy. I personally know many people (including me!) who started donating significantly because of EA.
