My wife sometimes provides medical care to "undocumented workers". She tells me stories of folks working 3 jobs, bosses who refuse to pay (illegals can't call the cops), working through hernias and other ailments, and all the while happy to be sending money back to their families elsewhere.

It's mind-boggling how bad it must be in some places. And yet, I'm sure that most residents of these "bad" places are probably happy day-to-day, hanging out with friends and family.
