I have not, its looks like its on Netflix’s though so I'll give it a watch. That said I am usually very skeptical of documentaries as a source of evidence.

I agree entirely with the listening aspect, this is why I really like GiveDirectly as a charity or developing capacity in a health system, rather than just building a hospital that then cannot be staffed.

It's hard we have so much money in comparison, there must be a way to use it so that it benefits others. Finding that however is extremely difficult.
