Why don't liberals all move to cuba?

its super socialists, it has amazing health care for everyone, nobody is rich there except the top people in government. they already taken everything they could from the rich. people there never have to worry about working or food. the government provides for everyone. every person is 100% equal and all have the same chance. does it get more socialist then cuba? if they don't like it they can build a boat and go take there chances at miami like everyone else,
