You're assuming the agents behind all of this actually believe in anything but power and wealth, and aren't just cynically rolling out the authoritarian playbook to justify why they have to seize it.
The ones that were just cynically using this popular sentiment for their own benefit were the previous wave.
But the problem with that kind of thing is that eventually it results in a wave of true believers. It doesn't mean that they stop padding their pockets, mind you - why would they, when they're obviously entitled to their fair share as the Champions of Something Great. But it vastly increases their capacity for damage because now they are going to do it even in situations where it doesn't benefit them in any way, and may even harm them, for the sake of their beliefs.
