the bolshevik revolution caused craziness and the revolution turned civil, stalin wanted more industries in the east which meant peasants had to become industrial workers, stalin delivered a speech telling them basically how important they were. and if they did not work then they would "be crushed"
It was harder to find jobs and less survival resources when moving to the coast. As America industrialized, the people started to migrate more towards the west especially when railroads were beginning to attach.
Well I can tell you that L'Ouverture lead the slave revolt in Haiti because I literally just took a quiz on that about 3 minutes ago. I really don't know about jean jacques. sorry
