I really like your comment as it is summing up one thing that I was thinking while reading and thinking about Courtney’s article: You have to start from somewhere. At some point there is nothing you know. -Neither about homeless people in America, the troubles of mentally ill in Germany nor about the problems in education in Mongolia.
I think the important point is to realise that things don’t change over night, that there are no simple solutions, that there is no problem that you can solve by coming over for 4 months to a country you’ve never been advising people on topics you are not an expert in. We should stop thinking that things that worked in one case need to work all over the world the same way.
