Lots of the South Vietnam Viet Cong leaders/organizers were upper class and educated in Paris as well.
Most them were kept out of power after the Communists took over. Many believed they were fighting for some kind of socialist democratic state -- they were duped by the northern Communists.
It's just the same that is happening today. If you want to create a socialist, send your son to Paris/London/Seattle. Send him to Cuba or Venezuela and you'll create the founder of the Next UBER.
