It's similar to their unironic use of "by your bootstraps."
That idiom was originally coined to indicate something that is impossible to have happened as claimed. Supposedly the story goes that there was once a general that would tell tons of tall tales and embellish his actions at every opportunity, and one time he recounted that he had fallen into a hole he couldn't climb out of, so he claims that he simply pulled himself out by his bootstraps. It literally violates Newton's third law.
So telling millenials or gen-z to "pull yourself up by your bootstraps" literally means the opposite of what they think it means. Either that or it's extremely subtle anticapitalist commentary, pointing out the fact that it's damn near impossible for the young generation to succeed under our current capitalist system, that's totally what boomers mean when they use that term right?
Repeating a lie gives it traction. We have electron microscopes and rovers on Mars, yet somehow still also people who think a sky fairy cooked the whole flat planet up 6000 years ago.
This is why we need to reinstate the Fairness Doctrine and expand it to the web space, allowing so many charlatans to scream their nonsense over and over has an effect on people. That’s why the rich cunts pour so much money into it
