that is the plan.  You can't just drag people off into concentration camps anymore, nor can you have death squads. People complain when you do these things. so how do you have an ethical genocide?  You promote self destruction.  You get the undesirables to kill themselves off with food and drugs, and you profit off of it. All the while pointing out to the survivors: I told them it was bad, they did it anyway, now they are dead.
