I would say that the ability of people to agree on matters of fact not immediately visible — states of affairs removed from them in space and time — ramped up from a baseline of approximately zero to a pretty high level around the time of the scientific revolution and all that, and stayed there and became more globally distributed up through the Cronkite era, and then dropped to zero incredibly quickly when the Internet came along. And I think that the main thing it conferred on people was social mobility, so that if you were a smart kid growing up on a farm in Kansas or a slum in India you had a chance to do something interesting with your life. Before it — before that three-hundred-year run when there was a way for people to agree on facts — we had kings and warlords and rigid social hierarchy. During it, a lot of brainpower got unlocked and things got a lot better materially. A lot better. Now we’re back in a situation where the people who have the power and the money can get what they want by dictating what the mass of people ought to believe.

...class is more than income - it has to do with knowing where you stand in a web of social relationships.
