Completely isolated == easily homogenized

I've always wondered why Chinese people living in mainland China seem so much less propagandized than Americans. I think I finally found a possible answer while listening to historian Darryl Cooper interviewed by Tucker Carlson.

...go back to the internal migrations in the 20th century after the Second World War, like in the United States, and the way that the internal migrations were used to break up these traditional Catholic parish communities in city after city after city around the country. And done so, I mean, we know this from documentation, that this was something that they knew what they were doing. They knew they were breaking up these communities that they saw as pools of insularity, these black boxes that the system itself couldn't really see into and didn't exactly know what was going on.

Because when you break up, say, those parish communities, you drive everybody out to the suburbs, everybody's living within their own fence line now. They're not living in a community, they're living in their own fence line. They maybe don't even know their neighbor's names.

You have all of these people who are completely isolated and easily homogenized over time. And, you know, they lose their distinctiveness and become, and melt into a part of a mass that you can now propagandize on a mass level in a way that, you think about it like, if you lived in a parish community back in the 1920s in the United States, you lived in an Irish parish community in New York City, and the government was, or the culture, whatever outside force it is, is trying to propagandize you in a given way that your grandfather and your priest and the elders in your community, that everybody respects, are all telling you is not true. You're not going to believe that.

Americans in the post-WWII 20th century were intentionally pushed out of their trusted communities and forced (via racial violence in cities) to live in isolating suburbs where mainstream media became their main and often only source of information.

Chinese, in comparison, haven't been forced out of their cities or communities by violence. Every city square in the country has hundreds or thousands of aunties and uncles dancing to music every night and sharing the latest gossip. Multiple generations often live together or nearby. While there is the government-approved media, it is supplemented by communication that happens in physical, in person communities. And in densely populated cities, you can't help but encounter strangers through taxis and stores and restaurants that have their own take on the official narrative of what's happening in the world and can't wait to share it with you. Just take a Beijing taxi.
