To answer to Dada Giri's question about why we at least I am not ready to clean toilets in Mugling and Tri-Chandra, well it is not necessary. In nepal, my parent's earnings is enough to pay for my college tuition, but in US it is not. Do you think I would be cleaning toilets, are will be working for a low paying jobs here in US, had my parents been rich enough to afford my educational expenses, or if I had recieved some kind of scholarship and stipend? Hell No. And in the same manner, if I had no money, my parents had no money, to help my education in Nepal, I would have surely picked up odd jobs to finance my education. It is that simple. Necessity if the mother of invention, or in this case the mother of cheap labor.
