In my opinion, all this is happening because people have nothing, absolutely, NOTHING to do. If everyone is busy there would be less chaos. I think what we need to do is bring economic revolution. But how? Well, the dollars you sent home can be used very wisely. Number of people working in other countries can form some kind of industry small or big, and employee atleast some nepalis there, could be 1, 10, 100 or more...if everyone abroad stopped building non-sense big ass house and land, and rather invested in some form of productive industry in long-run eventually there would be happiness and peace.
