Still, if Cuba ever opens up, it's going to turn out to be a lot worse than many people think. Guys, if people take a major risk of dying to get out of a place, it's bad. It doesn't matter what the health care system or the literacy rate is, there's something very wrong.
While I'm strongly opposed to the embargo-- it's an massive infringement of freedom for Cubans, and a presumptuous one for Americans, it's far from the whole reason Cuba is so impoverished. Cuba is free to trade with the rest of the world, and if Cuba had much worth selling, it would get smuggled into the US.
