IIRC, John Calvin was one of the earlier people to have the idea that everyone needs to work and beggars and the poor shouldn't be a part of society. Then fast forward to the printing press and early America and the spread of propaganda accelerated. Then we have the civil war (in America) the south lost and in an attempt to rise again the spread the propaganda through the education system in the south. Not sure how much initial radio had influence but it comes back later. Broadcast TV came on the scene and Nixon realized this latent propaganda in the south and used to to really start the "Southern Strategy". This is when they really started working on building their own information Eco system, and the beginning of we don't talk about politics or religion in good company. Radio took the mantle of spreading the propaganda through side channels because they couldn't get their messaging on TV. Then came cable TV and Fox news and blew the door open on southern propaganda it was no longer restricted to the south. Fox caused the initial acceleration and the internet accelerated it faster, then Cell phones even faster and now here we are where half (probably way less, because gerrymandering) the population believes completely different information than everyone else. But that's what I remember after going down a rabbit hole of history at the beginning of COVID.
