How a nation can spout off about it's sovereignty one minute, then claim the reason they're destitute is because we won't play nice with them the next is a larf to me!
Seriously, Canadians can go there, Europeans can go there, South Americans can go there, I'm assuming most Asians can go there as well. Unless THE REST OF THE WORLD has embargoed Cuba, I don't really see our refusal to deal with them as being the root cause of their poverty. I mean, it's not as if we've got destroyers hanging off their ports, sinking foreign merchants on their way in.
This is not to say that the embargo makes a lot of sense to me at this point. After all, if we can deal with North Korea and China, then Cuba shouldn't be a problem. But let's not kid ourselves here: Cuba's government is the root problem with Cuba's economy. Cuba won't get better until they shed the failed Marxist policies they continue to employ, despite the distinct LACK of empirical evidence to support the theories of Marxist Communism/Socialism.
However, once this happens, I believe Cuba will have a bright future! I'd love to move there, just to get away from the slow-driving snowbirds, and the mentally unstable Florida Crackers!
