About a quarter of the population struggles to keep up, but that's the same across time and cultures. 75% of people, when polled in the US know their basic history, just like 75% of people know it in Germany and Great Britain. No matter what culture you sample, 25% of the people believe in alien visitation, or the sun revolves around the earth, or that dinosaurs walked with Jesus, and that's just the way it is. Julius Caesar complained about the 25% of his own population that was lazy and clueless. That's just the way it is.
So you go to the beach, or on the sidewalk in Manhattan, and save 1 out of 4 interviews you record, string them together, and then we can all shamelessly pat ourselves on the back for not being ignorant, and shaking our fists at social decline, and then we can get the tiny little dopamine hit for the nostalgia of remembering the imaginary golden age we pretend we came from.
