Many Cubans in Florida either fled Cuba following the Cuban revolution or are the children/grandchildren of those who did. Those that fled obviously disagreed with the Castro regime so vehemently they left their homelands, friends, and family behind. Very often they were the middle, upper-middle, or upper class of Cuba, so when the socialist revolution nationalized private property, disrupted private businesses, and seized private financial assets, the Cubans that fled were the ones that lost the most. Others fled due to political persecution and imprisonment, censorship, etc. Cuba, like anywhere else, wasn't and isn't idyllic.
