It's almost not the embargo. It's the Cuban government behavior. They're just criminals who manage a state-monopolistic capitalist country.

It has never been real socialism, but now it's very far from it, with the state only investing (wasting) money for building big hotels where no one go (occupation around 20% in high season across the island) and leaving population in hanger and without any basic public service.

Meanwhile the new little (till 250 employees) private companies import anything from anywhere through corruption, reselling goods at crazy prices that only rich cubans can achieve. No embargo does not exist for them. While society gap is everyday higher.
