Wow. That is the most reductive analysis I think I have ever seen. So people can end up vulnerable in both?
Its simply intellectually lazy to say "people under socialism are vulnerable". No, the citizens of Cuba are not vulnerable, they are desperate. So desperate, they band together pieces of trash to form rafts and take to the ocean to flee in hopes of a better life in the USA. I don't see people in the USA fleeing to Canada or Mexico to escape oppression in the USA.
