Economic refugees or economic migrants exist all over the world and there are many trying to get by in Mexico.

We became friends with a family while on a holiday there a few years ago.  The couple had a baby and another coming.  The town was full of wealthy tourists living in "time shares" and enjoying the beaches and warmth.  The father in this family worked from dawn to dusk, literally, selling tickets to time-share gatherings,  He had to sell so many a day in order to keep the 1-room windowless place they called home.  He worked at a restaurant and bar in the evening and received no pay at all, just the tips he was given.  He was grateful for this "job".  

The Catholic Church that my daughter and I attended on Sunday passed around a tupperware dish....there were 2 - $1.00 bills put there by tourists and the church was packed.  I suppose that's why tourists prefer "all-inclusives"--no need to face reality.
