It seems to me that most responses have bought the US Democrats and CNN talking points saying that people are demonstrating due to COVID and the embargo. They demonstrate shouting "libertad"! Which means freedom or liberty, so it doesn't seem to me that corresponds to what CNN says.
What does seem to me is that we are back to the same thing. In Cuba it is the embargo, in Venezuela, the USA also put sanctions but the fact is that it never works.
During the cold war, a lot of communist nations were under the umbrella of the USSR. And they all ended up the same. Authoritarian, psychopathic regimes that were so wonderful that they had to build walls and fences to keep people from escaping how wonderful they were. The people who didn't die of murder or starvation ended up very poor. They were pretty egalitarian societies, that's for sure. You had the billionaire ruling politicians and then the rest, the vast majority of the population equally poor, and getting poorer and poorer. It culminated in the hyperinflationary collapse of the USSR.
What do we see today in Cuba or Venezuela? It seems to me that they can be compared, because at the end of the day, to compare is to find similarities and differences.
Authoritarian regimes, massive and generalized (egalitarian) impoverishment of the population, apart from the multimillionaire ruling class, massive exodus of the population...
By the end of 2020, 3.9 million Venezuelans were designated as being displaced abroad without formal refugee status.To see how wonderful these regimes are you only have to look at how many people escape from Cuba to the US and how many escape from that racist, unequal and oppressive trash of a country that is the US to Cuba. Or how many escape from North Korea to South Korea and the other way around, etc.
Cuba is the classic example of how socialism works. Fidel Castro came to power by promising wealth redistribution. And he kept his promise after getting power, by seizing all the privately owned businesses. The previously wealthy upper class suddenly found themselves on the street without any money and the only option left for them was to immigrate to Florida and some of the other US states. A few decades later, these refugees have become one of the wealthiest demographic groups in the US, while those who remained in Cuba to support the socialist policies are now some of the poorest people in the globe.
This sums it all up.
