Fear, exhaustion, incessant propaganda, existential dread, etc. Most people don't care if their leaders are literal saints or if they kick babies. As long as it wasn't their baby and they can keep their porn, sportsball, corn syrup, Soma, and watch some devil spout gibberish on the idiot box they'll count their blessings that they aren't in Africa. That said most folks are less ignorant than people assume. They just assume, probably accurately, that they'll be incapable of taking care of their families/themselves if order is disrupted more than it already is. Take away a persons sense of stability and they'll run into the arms of their tribe. Running into the arms of your tribe isn't necessarily a bad thing, a lot of folks just chose shitty tribes.
