which are these most international development orgs that focus on pouring money into infrastructure? UN orgs beg for money which mostly funds humanitarian work, food security, poverty alleviation. USG throws it all into health systems under the guise of AIDS prevention, with an okay chunk for economic growth - mostly agriculture market systems. JICA does mostly agriculture, health, education human capital building. other orgs I've known throw it many places. You can get EU reports on funding across sectors. It's been my understanding, at least in the few countries I've read about or lived in in Africa, that host countries would love infrastructure and most international development orgs avoid it like the plague. When they do it, then it is big money, because it costs big money. But I don't think they actually do it often. Where do you get the idea that most such orgs do infrastructure?

and on PC - I always felt it was cultural exchange - peace and friendship - like Rotary with a twist. We just keep the first objective to have an explanation for why we're hanging out in the village for two years. As in, PC and USAID were created at the same time, and one of them was intended for 'development' while the other was intended for 'peace'.
