World Banker and His Cash Return Home -- This article from the New York Times, illustrates the migrant situation.

Some quotes that I thought were pertinent to all migrants:

With regards to remittances home:

Mr. Ratha has argued that the importance of the money exceeds its sheer size. Unlike foreign aid, it cannot be skimmed by potentates. Unlike investors who flee crises, migrants increase their giving during hard times. The money is directed to the needy. And Mr. Ratha contends it is well-monitored, too, by intimates on the sending end. “It comes with a lot of goodwill, advice, knowledge and punishment if necessary — keeping in mind the welfare of the recipient,” he said.

And there is common thing that resonates with almost every migrant:

Globe-trotting technocrat, village boy made good, Mr. Ratha is like many migrants torn between two worlds and fully at home in neither. “On bad days, I do feel lonely in a way that I can’t explain,” he said.
