Did you ever asked yourself "When does it end?". For a community to totally swift from low level, troubled, and kick start development has two things the community itself and the leaders it produces. There are two goods for a society or community and those are education and business which generate skills and produce jobs for the community but sometimes it is the mind concept of the people. If community looses leaders who drives it to good direction and create more of those that directs it in negative direction e.g. conflict, bad businesses, and create aggressive culture it is bound to loose more of her people. When a community is chaotic people tend to move to where it is peaceful hence draining it. Imagine a community with good businesses, education, NGOs and international organisation are driven away. It will create a vacuum and depopulation not only that, so is conflict.
