Personally,I don't think changing capital city will make much of a difference, the new city will simply turn out to be what Kathmandu is today. I think we need to de-centralize various levels of power and the way our economy works. I'd say we need to make other cities industrial cities, like what Hetauda and Biratnagar originally were (I am not sure about the current status). We basically need more industries to create more jobs. My two cents..
