When I was in Cuba, a lot of people I talked to were obviously in favor of lifting the embargo, but others expressed misgivings about what it would do to their culture and society. Cuba is an indescribably weird place where almost everybody is (on paper anyways) poor, yet education, health care and the arts flourish. Violent crime is virtually unheard of, say what you will about how they achieve that. They are very proud of their resilience in the face of a half-century's worth of crippling U.S. sanctions--in particular the period after the collapse of the Soviet Union. Normalization will lead to a rise in the Cuban material standard of living, and with it will come all of the attendant social woes that we have here. That's neither totally good nor totally bad, and it should be up to the Cuban people to choose their own path, but I can see why you might oppose this for other than purely selfish reasons.
