That's a great point I had not thought enough about, and I think you are correct.
Certainly your examples of health (disease and sight) sound very positive.
Also examples where NGOs or World Vision or whoever bring in massive quantities of food appear very positive on the surface, though the long term consequences are extremely unhealthy, and just create more of a dependence loop than ever before, until locals are utterly unable to help themselves.
> Donors are helping, but maybe not as much as they think they are (per dollar). It would be great if they would research the org they are donating to to find how many cents per dollar are going to the cause. More transparency in this area is needed.
More transparency is absolutely the key, but I also think it's really important to take a step back and really think about if and how any donor is actually "helping" at all. We in the west have this funny idea that money is the answer to everything and more money = a better life. Certainly it's important to have healthcare and clean drinking water, but after that a lot of times I saw money degrading African society, not making anything better at all.
I'm terrified we'll turn many special countries into "little America" or "little Europe" complete with high cancer rates, stress, 9-5 jobs, pollution, lack of care for our community and neighbors, high crime, rampant greed and inequality ,etc. etc.
