Bureaucracy is low beta: stability.

Authoritarianism is high beta... but the inherent lack of self-ground-truthing makes them tend towards an auto-corrupting end state.

Everything is at the whim of the authoritarian, and those whims can change on a dime.

Everyone--all of society--needs to pay careful attention to the whims of the authoritarian to avoid crossing him.

Huge segments of the society's mental energy caught up in that.

Bureaucracies are boring but also stable, easier to predict what they'll do.

So you can free up your mental energy to take them for granted.
