If Caribny think that he as a black man will have more opportunities with the white Miami Cubans than with the Cuban revolution then he should go and work for the White Cubans in Miami.
BLACK Cubans say that white Cubans are NO different in Miami OR in Havana. Take a read of articles written by Carlos Moore. There was a symposium on racism among Cubans which I attended at the invitation of a black Cuban friend of mine. The black Cubans tongue lashed both the exiles and the Cuban elite.
You may not know this but many of the Cuban oligarchs in Havana are related to those in Miami!
