American interests in Cuba had been to a great extent gambling, nightclubs, prostitution, and other dark activities. Castro did largely end this, making an enemy of the American Mafia interests who owned what had been goldmines. He rescued his nation from being an off-shore dyonisian playground where US citizens from the bible belt states could hide their sins from their neighbours. Walking off a ship in Havana now, one no longer has to run the gauntlet of a long avenue of brothels. It remains to be seen if his brother Raul can set his free people from himself whilst keeping them from being enslaved (again) by US dollars.
