Orphans of Liberty have published a piece on the self-perpetuating nature of most charity work.
They start with the example of Ethiopia; Band-Aid did great work in raising funds, finding food, and supplying it to the starving. As OoL point out, though, nothing was done to address the basic problem that the area was still not very fertile but now had free food. So while we should be encouraging people to move away to somewhere more fertile, we were in fact attracting people in.
Their other example is homelessness in London, suggesting that by making homelessness a less painful option, we draw people in to a situation where their prospects are non-existent. If homelessness was more scary, goes the logic, more youngsters would stay at home until they could find and fund a bedsit - from where they could actually progress.
I can follow the logic, but I don't like where it leads us.
