There are no rich people and there are no poor people
That is just not true. In central Havana, there are buildings that are literally crumbling - they couldn't exist in a Western city, they'd be condemned and torn down, but there are three families crammed in there, electrical cables strung across the street, corrugated aluminium in place of glass in the windows, wooden door and window frames rotting. . But if you head out to the suburbs and have dinner at a paladar, there're people living one family in a gorgeous Spanish colonial mansion with landscaped garden, a pond and a gazebo, who want for nothing and amuse themselves by entertaining Western guests.
In a society where everyone is equal - how do you get that?
