Humans aren't stupid. Most of us can realize the majority of the failings in almost any societal system and point them out by instinct.

The issue is, humans hate to be hypocrites. So they will suppress any amount of noticing they do to make sure they don't implicate themselves when calling things out. Its self retarding to keep your moral highground.

That's why all the Lefties will crow about every type of injustice under the sun. Except classism, because that would require them to not only acknowledge their extreme flaw but be compelled by basic human morality to correct by giving up their cushy life.

Worse yet, many times they aren't even doing it deliberately at the outset. The brain is a shitty little organ that will absolutely do that shit for you, because it wants to avoid anxiety and challenge. It'll outright delete that information from your mind to keep it from taking hold, just like it deletes your nose from your vision every moment of the day.
