> most people I ran at work into were not specially educated
We're talking about an historic timescale. If they are literate and have high school degrees, they are very well educated compared to pre-industrial people.
> woman in charge of my office bowed down in excuses after a lawyer insulted her for his own mistake. This is the sort of power people still don't have and that no book will teach you.
