It would be really hard to rebuild a government after all the corruption that the country has already been through. but if you got a leader dedicated enough, that wants to do the right things then I think it could be done over the course of a few years. I thought it was super lame how the teachers would show up then just leave again. the real question is why didn't they stay? I certainly don't know much about the situation, but it seems as if its getting better.
