You should also watch Empire Of Dust. Its a documentary following around a project manager for a Chinese mining company rebuilding a road through a Congolese area in Africa. The Chinese man has an interpreter with him called "Dragon". During one of their trips the Chinese guy points out the railroad parallel with the vehicle road they are driving on and says that it was built by the Belgians in the 1930s during their colonial expansion in Congo and the Congolese just let it fall to shambles. He points out that it was advanced at the time and the Chinese didnt even have railroads in the 1930s.

Even with advanced technology and all the support in the world, some people still cannot make or keep a functioning society.
