The more they divide people the more pure blood people will be free not in the crowded city centers but in the fields. Also those brainwashed people will be retarded or crippled if they can survive from various parasite injections. And they will demand natural food from pure blooded people. Because they can't go to the field and actualy do any kind of real work. They will beg for geting some food. Their currencies not gonna have any value and also at that point good people who have been stabbed from their own governments won't allow currencies of those governments to exchange their product, time and effort. So either they have to use digital currencies or they will have to eat some weird organisms and fake meat to survive.
