The founder of our nation knew this problem and he tried to minimize in different way and it worked just until bahadur shah was politically powerful. Industrialization in the europe brought modernisation of world and different thinking and they were experiencing different kind of political system and at the time rana were in power and they only thought how to be remain in power and they had closed the borders as everybody reads in history books. there should have been some kind of scientific revolution in nepal, mainly BP should have take extreme measures against feudalism. they say BP is a great leader but he could not solve the problems he was asked to solve by the people. and he let that feudal system come into the political arena and dirt it again from its roots and then again they get those chances to deep root into our system of life. i don't think ethnicity would be a big problem if people get aware about the game leaders are playing based on ethnicity, but turning back to the history pages we can find such civil wars of ethnicity and in present context we can talk about iraq. Iraq is a mess. and i don't think anybody in nepal wants to go that extreme. so everybody should forget the past and get united under one nation NEPAL, and find a way to solve our problem on our own field and not go to south and vomit over there, that gives a vulnabirity to our security. example recently one so called leader of madhesh did that and other leaders also have done more oftenly. Maoist are like poison to the society, slow poison you take it, its gonna hurt. there agenda are of too extreme measures to solve the problem, prachanda got the thinking of like pol pot in combodia.
