I read a profile a few years ago about a poor Mexican town whose male residents almost all spent the early part of their working years in one particular rural area of Delaware. They would work hard and send back a substantial amount to their families in their hometown, then they would return home a few years later with enough money to buy a home or open a business. I found it interesting that most expressed a sense of gratitude toward Delaware and the U.S., even though they were doing unenviable jobs and earning unenviable wages. But it certainly seems like there was still the potential for a type of arbitrage: earn as much as you can in a place where earnings are comparatively high, while keeping your cost of living as low as possible, and then take all your savings back home, where the money goes a lot farther.
