You are missing the other half of it. The cubans that stayed, hate the cubans in Florida as much as the cubans in Florida hate the cubans that stayed.
Many of the Cubans in Cuba want to join the Cubans in Florida, thousands of them try every year. The Cubans in Florida don't hate the Cubans in Cuba, they are opposed to the communist government that is oppressing their friends and family back in Cuba.
The easiest way out for Cuba is to turn away from Communism. It is one of the last hold-outs on the planet in inflicting that failed system on its people. Activists in Cuba support the continuance of the embargo.
The Time to Help Cuba’s Brave Dissidents Is Now: Why the Embargo Must Not be Lifted
Another brave group of Cuban opponents of the regime has actually taped a television interview filmed illegally in Havana. “Young Cuban democracy leader Antonio Rodiles,” an American support group called Capitol Hill Cubans has reported, “has just released the latest episode of his civil society project Estado de Sats (filmed within Cuba), where he discusses the importance U.S. sanctions policy with two of Cuba’s most renowned opposition activists and former political prisoners, Guillermo Fariñas and Jose Daniel Ferrer.”
The argument they present is aimed directly at those on the left in the United States, some of whom think they are helping democracy in Cuba by calling for an end to the embargo. In strong and clear language, the two dissidents say the following:
If at this time, the [economic] need of the Cuban government is satisfied through financial credits and the lifting of the embargo, repression would increase, it would allow for a continuation of the Castro’s society, totalitarianism would strengthen its hold and philosophically, it would just be immoral If you did an opinion poll among Cuban opposition activists, the majority would be in favor of not lifting the embargo.
Next, they nail the claim that travel without restrictions by citizens of our country to Cuba would help spread freedom. The men respond:
In a cost-benefit analysis, travel to Cuba by Americans would be of greatest benefit to the Castro regime, while the Cuban people would be the least to benefit. With all of the controls and the totalitarian system of the government, it would be perfectly able to control such travel.
We know this, as I reported a few months ago, about how a group of Americans taking the usual state-controlled Potemkin village tour came back raving about how wonderful and free Cuba is, and how Cuban socialism works.
Finally, the two former prisoners made this point about lifting the embargo:
To lift the embargo at this time would be very prejudicial to us. The government prioritizes all of the institutions that guarantee its hold on power. The regime’s political police and its jailers receive a much higher salary and privileges than a doctor or engineer, or than any other worker that benefits society. We’ve all seen municipalities with no fuel for an ambulance, yet with 10, 15, 20, 50 cars full of fuel ready to go repress peaceful human rights activists.
