This "job maker and job taker" is really a nothing point to be quite honest. 

A country's economy depends on how much people spend. The more the people make, the more they spend - thats what ultimately leads to job growth.

So say, Mr. X is super talented but has no decent financial backing except for a piece of land in Gorkha. What and how is he gonna generate more jobs, I really wonder. 

Also, this "if you're mediocre, you're better off living in the States" is bogus too. Well, Bogus would be a harsh term, perhaps but its nothing but a mere personal opinion that's demoralizing to say the least. A person's ability isn't to be judged upon his GPA or track record. 

People change overnight as situations arise. 

Prior to my departure for the States, all I could cook were an Omelette and noodles but by the time I made my return, I was a decent cook. Had I stayed here, I doubt I'd have made any progresses in my culinary skills but again, situations changed me. 

At the end of the day, again, I repeat, if you're really determined to succeed in Nepal, you'll do it, eventually but unless you've got at least a decent financial backing, you'll be cussing yourself if you left the States ( provided that you had a decent job already ).
