I remember going to college where there was a good number of Vietamese, mostly second generation, who were young when they boarded the boats and made it to the shores of America. Long story short: the communists would come to their village and tell them that all would have a job, crime would be eliminated, all would be schooled, all would be treated equally, blah, blah, blah.
Upon taking over, the communists would assign everyone a job, like it or not. Many were sent to the military. Some were forced to teach-that is, be indoctranated and regurgitate. Farmers were firmly regulated to provide for everyone, and so forth. Anyone who had commited a crime was arrested and sent away. No more crime. All children were schooled, that is, completely inculcated into the communist way. Any resistance was treated harshly, but equally. And so on.
I never forgot that.
