I'm going to give you the benefit of the doubt and assume that you have good intentions at heart but are somehow misled as to how societies work. I will try to remedy that.

Nepal by no means has "failed to organize even a bus terminal". For god's sake, the Nepalese people organized a pretty successful resistance against their Monarchy[0]. So please get your facts straight before making such sweeping generalizations about 3rd world countries. In general, every country has a very unique set of circumstances for being in a state of social/economic/political backwardness.
