Why Don't They Care?

I think part of it is indeed corruption, though in this case on a personal level (the workers are being paid, they just aren't doing their jobs unless they get an additional stipend for each individual task).

I think part is indeed desperation and raw human nature - you understand that when you see how little some people have, the kind of conditions they live in, and what they do to try to get food and water that won't poison them.  Everybody lives in the center of their own series of concentric circles of loyalty (I assume unless you have children, then you probably live in ring two).

I think part is the culture the industrialized world has created by handing out hundreds of billions of dollars over the last 50 years without any accountability for results or incentives for performance (to Chris Sang's point).

I also think part is what the director of UNICEF's nutrition programs told us today - "We (as a development community) spend all our resources addressing the immediate causes of death.  We're pulling kids back from the brink, but there's nobody there to catch them."
