I don't know for sure what the country is like, but if you look at stories about Cuba in western films, they do live more freely and naturally, the investment world is also more speculative and volatile. It will be more possible for the whales to be wild in spreading rumors to take advantage, meaning who is the strongest, then he gets the big profit. But I emphasize that this is still just my speculation, it can be refuted because the basis is not strong.
I can add a little - I know Cuba not from films. At one time my father served there (when he served in the Soviet Army) and talked about Cuba. And I myself, already in modern times, rested there 2 times. Frankly, not a single feature film is close to reality, and even more so it does not show all aspects of the life of ordinary people in Cuba and the country as a whole.
