Besides ideological self-righteousness, Aaronson left out one important component of oppressive regimes, which I think is actually far more important: it takes a relatively large amount of people to topple a regime, while small groups as well as individuals do nothing but expose themselves by rebelling. So no individual with any regard for his own personal safety has any incentive to rebel, and will instead go along with the flow for as long as it's tolerable to him.

But this, on the other hand, would create an odd situation where actually the vast majority of people might actually wish for rebellion, but none of them actually acts out on that wish. Which I also think is actually much more likelier than what he's putting forward. True crusaders are rare, most of people are "just following orders".
