Re: Post-truth
That description of the population hasn't really changed in centuries, though. OK, maybe tax wasn't something that bothered ordinary folks until the "temporary" introduction of income tax to pay for the Napoleonic wars, but the rest aren't new.
Every government is accused of screwing up the education system, yet 200 years ago fewer people were literate and numerate. Confirmation bias has always been around, but in the past it just meant that all your mates in the village pub agreed with you that the landowner was a bastard.
Terorism wasn't a thing, but scare stories about immigration have been around forever, it's just that the "immigrants" were the clan from the next village who ate babies and would steal your daughters.
If anything, the big difference today is that we all have a bigger view. News from outside our town or village no longer travels at the speed of a horse, we're swamped by it every minute of the day, and we're made to feel that it's important. The apparent scope of the "problems" has expanded.
Politics today is just as much lies as it ever was, I don't really think things were more subtle in the past. There was nothing subtle about hellfire preachers forecasting eternal damnation for anyone who criticised the church or the King.
If anything, past control of ordinary folks was based more on fear; transportation or hanging for petty theft, maiming for poaching, etc. No need for subtlety or lies when you could just whack a peasant's hand off for scratching his arse in front of you.
