Lets put this way, in few years, i have sent back home the amount 100 times the value than what i would have earned in Nepal in few decades and that money is not being deposited in a bank, they are for expenses and have been spent, circulated through Nepalese market. So i can proudly say by living in US, my personal contribution for increasing Nepals economy is 100 times more compared to if i was living in Nepal.
Remember again, remittance is the major source of income for Nepal.
