This is my reason why there is less. However we are learning its potential and more Nepali are getting into. It is a skill that we don't foster back in Nepal. I mean I have seen plenty of Ph D candidate who have never used a drill in their life. We grow up not even using a simple tool. A new Nepali will have no clue about anything in a Home Depot. We expect our kids to be engineer and doctors but carpenter, plumber are not the proudest job that our parents are willing to brag about. But things are changing and more will join this profession. I have seen construction worker and few mechanics but not whole lot of carpenter and plumbers. It will take time.
