Think Niger. Think poverty. Think backwardness. Think filth. However like any other place Niger will have doctors, engineers, accountants, mathematicians, writers, dentists, chemical engineers, computer engineers. What if it just exported 10% of them to USA what would happen?
Every time you ran into somebody from Niger he or she would invariably be a professional. The stats for people from Niger in USA would be impressive. Back in Niger though rest of the majority from would living in filth. The sample from Niger would be so to say cherrypicked . However this small group from NIger would make no impact on USA because their relative numbers would be minuscule.
Now what if Niger has only population of 17 million., compared to India's nearly 1,300 million. What if you multiply Niger by 76 times. Now that tiny professional sample fron Niger living in USA would grow by factor of 76 times and it would have very stromg impact on USA.
But Niger would still be a swamp poor and filty country - only filth also would explode by factor of 76 times. You have your Shining India ladies and gents.
Just another oversized Niger.
