Here's a specific one that we are told about history: that we work less than our ancestors did thanks to automation and labor-saving devices. Truth is that the period of history (granted I'm talking specifically about European history) where people did the least amount of work per year was probably the middle ages (the other top contender for "least work required to live" is hunter-gatherer societies), until right before the industrial revolution. The industrial revolution sees people go from working for about half the year to working through the entire year, and from having relatively slow schedules to absolutely brutal ones. Kids went from working half days (when they worked at all) to working full time, and the compensation everyone got bought them fewer luxuries than their grandparents had when they were literally peasants.

There's been some clawing back of our lost free time in the past century - and without modern productivity many of the things we take for granted simply wouldn't exist - but we're still pretty deep in the red compared to back then, and of course there are plenty of places in the world where working conditions are still comparable to the worst times of the industrial revolution. I'm not a "Retvrn" guy but I think this bit of context regarding modern work culture compared to the ten thousand years preceding it is something everyone should know, but that our society constantly paints over with misrepresentations of what the past looked like.
