I wonder what Cuba would look like now if Batista had never been overthrown. That's probably on par with how it would have worked if US meddling were more successful. I can't say I know it would be worse.
Difficult to separate "Cuba is bad because it is badly governed" from "Cuba is bad because it has been heavily sanctioned and no longer gets help from the Soviet Union", really. Too many different variables. Hard to imagine it being worse than Haiti or El Salvador, but also hard to imagine it having free elections (because that would immediately elect an anti-US socialist who would be overthrown again).
