This is a good question, but it's also kind of tricky because many (maybe most) social charities aren't really setup to tackle issues that can be solved without continuing money input. Let's take education in poor countries as an example - unless everyone stops having children or the underlying socioeconomic fabric changes significantly, you're going to have an effectively infinite number of children that need to be educated, and the only way to do that is to continue paying for facilities, teachers, materials, etc. Other charities, like those that are setup to cure specific illnesses, can accomplish their mission on reasonable timeframes.
