Can you explain how in your understanding a ban on leaving your country - as NK, Cuba and USSR did - has anything to do with social justice? How do you explain & justify this? You call yourself a socialist - is forcibly keeping people in a country part of your socialism?
I'm genuinely interested. I've read a lot of justifications for why there's nothing wrong with living at $20/month in 70's Poland from people like JP Sartre living in $2000/pm France.
