When did Uncle Luke become a reporter? I remember reading an article of his years ago thinking it was just a one-off editorial, but he's actually writing articles and being taken seriously. Wow.
If you look over Cuban immigration history, pay attention to the exodus right after Castro took over. The wealthy Cubans fled because they knew the party was over. These were mainly the Spaniard children of the former Spaniard landowners /plantation owners. aka white people.
In every caribbean or south american country, the rich elite families are descended from the former plantation owners and tend to have mostly spaniard blood if not full spaniard(or french or portuguese depending on the country)
cuba is the exception in that the "elite" are here after fleeing castro, most other places...rich elite class is still there
