Interesting comment, "survivors."
What rings true is that the DR is not for everybody. Some can adapt and thrive, I'd say most cannot.
Warm weather and palm trees only go so far.
It is a definite compromise for me. I am from New York State. Upstate, far upstate. I never liked it there. I just hated the bad weather virtually all year long. I moved eventually to California. By far and away the best place I lived, but to remain there was just too expensive. I was supposed to end up retired in Sri Lanka, but that was not to be after my wife from there died young. I ended up in the DR to stretch the dollars, but the DR will also stretch your patience. There are always trade offs.
