I think yesterday's New York Times article about Cuba misses its true potential. Sure, Cuba will become a major travel destination once Castro is gone and these silly sanctions end, but the real potential for Cuba is to become the number one retirement destination for aging Americans.
There is already a movement to retire south of the border to stretch ever shrinking retirement benefits, but Cuba has something the rest of Latin America lacks, some of the finest affordable health care in the Western Hemisphere. Hell, they have a lower infant mortality rate than the US.
All that this requires is for the United States to reverse 46 years of failed policy. That reversal would certainly bring some new players to the table to lobby their position. Big Pharma for instance? I can't imagine they want a couple of million customers getting on the socialized medicine bandwagon.
