Dude, "Peasant Brain" has been around for thousands of years.

When you have a society run by some of the most mentally unhealthy people to ever live, things are going to be pretty jacked up downstream of that. Can't undo thousands of years of social conditioning in a few decades (here in the west anyway, much of Asia, pre-genocide America/South America and the like did not live under such nonsensical societal structures).

This was all part of the plan, and they've been broadcasting it to our faces forever. Eliminate education, create extreme division within the other class, use racial animous to prevent White men especially from questioning their doublethink, pay off the liberals in power to maintain the status quo, and conservatives to push the window further and further in their favor. But remember that these people are slightly incompetent, and the descendants of inbreds. They're mentally unwell and not the most intelligent people. This leads us to them openly and blatantly failing to cover their own tracks. Whenever I hear a conspiracy about a "secret cabal" I cringe. There is nothing secret about any of it. It's all out there. These people thought that they were so far above us that they'd have absolutely no consequences come to bear.

They also just kept pushing the needle. This is a historical constant. The entire idea of Capitalism was to maintain that status quo power dynamic (the same dynamic that existed under the monarchs) by utilizing liberalism to prevent significant change to the body politic. However, this required the ruling class to make occasional concessions... something that, even when for their own sake, they increasingly grew unwilling to do. This also provides some insight to the kind of greed at play here. Completely pathological depravity. No rhyme or reason beyond a near clinical "need" and a sociopathic sense of being "deserving" and "above" everyone else. They kept pushing the window far further to the right than it was intended to go. They were always destined to do this. Capitalism only has one end, much as the feudal systems before it... fascism. Once you understand the motives at play and the functions of the system the outcomes become inevitable.

As for why so many people are so susceptible to the ruling classes nonsense... well, first you have to understand that they always have been. Replace the theocratic monarchies of old, and the disseminated teachings that god ordained those monarchs to rule over you, for better or for worse, with the alter of the economy, and the idea of meritocracy.

The second thing to understand is that these mentalities were developed over time, as with the peasant class. People were born and raised with conservative, "patriotic" values, often imbued with racial animous and stereotypes and linked heavily with imagery of a lifestyle they've been told they are supposed to and deserve to live. Then, Capitalism is simultaneously destroying the social and economic fabric of their communities and making life progressively more difficult as time marches on, lending false credence to the racial animous and bigoted values that were instilled in them at birth. Then they are told by their leaders, their religion, and their upbringings that those people who stand aesthetically with them and are clearly far more successful are meant to be. That god, or the power of their own free will powered their financial success. I think you can see where this is all headed. When time comes for these people to question anything, they're primed and ready for their brains to effectively just snap on the inside. Their entire worldview, ideology, thought processes, opinions of others, and the communities around them, and the nostalgic media they had consumed, are all now showing themselves for what they truly are, and for a lot of people, fight or flight when it comes to these types of situations, is automatically flight. So they double down. Fall deeper into their immaterial understanding of the world and have the perfect safety net of bigotry and hatred to maintain their delusional state. It's the easy road out, and it's what's comfortable to them.

The third thing to understand is the education aspect. By eliminating proper education on the subject matter at hand, any chance for the right questions to be asked early enough is also eliminated.

A material understanding of politics and the world is the key to waking people up... sadly that is easier said than done.

I hope this gives some insight into the minds of these people. I found this post at 6AM after a night out with the boys lol, so typing, spelling, and just in general the whole reply probably aren't done well.
