Here's another bogey -
Cuba is beautiful, the government is bad and the people suffer terribly - it's sad. Not that this bothers anyone outside the US that takes advantage of cheap vacations to be had. BTW, the money skips over the "regular" Cubans and is directed to the Communist Party elitists. Even in poor countries there are wealthy people. The wealthy are picked by the elite ruling class in Cuba, you can't earn your wealth.
The Cuban people are, by and large, poor. However, to say they suffer terribly isn't entirely accurate. They are a very happy people, they are fed and housed by the state, and their health care, although not great, is also paid for.
As for wealth in Cuba - Raoul Castro has opened up opportunities for Cubans to start their own small businesses - in home restaurants, driving one of the ancient American cars as a cab, etc. These people are starting to realize that they can get ahead. Also, Cubans working in tourism do well from tips, etc., and many highly educated Cubans - lawyers, teachers, etc., opt to work in tourism for that reason.
Finally, Cubans with American family often receive money and goods from their families, allowing them to live better than the average Cuban. While these three groups do not approach the wealth of the Castro brothers - who live in immense estates just a short distance from Marina Hemingway - in my opinion, the changes in levels of wealth amongst average Cubans will, in the long run, be the death of the Communist system there.
Will that change Cuba in other ways? Not necessarily - take a look at China, which has opted for capitalism while continuing rigid state control of everything else. That seems to be the way Raoul is taking Cuba. Time will tell.
