What you say about their life in Nepal? Won't they have lavish life in Nepal? Ready made job for them. 
No matter what at least they are back rich or poor to be with their aging parents, to enjoy all the festivals, to enjoy gossiping relatives hahahaha. 

America is a torture for old parents. And you will be old one day alone in nursing home. That is why all these old NRN want dual citizen as they are tired of lonely American life. May be. They have money but.no one to show off those achievements.
