Not sure where you see assumptions. There are many possible problems, and I don't know OP's situation, which is why I was asking what is the main problem there. Sometimes it's teachers. Sometimes it's textbooks. Sometimes it's not having a roof above your head. Sometimes the kids are starving and can't focus on the lessons. Sometimes it's different language.

One possible reason is that some of them could be born there. Again, this differs between communities. Some of them respect their smartest members. Some kick them out.
