I mean, education spending in inflation-adjusted dollars has increased steadily for the past 30 years, except for a temporary dip under the messiah Obama. But don't let a silly thing like your argument being based on completely wrong information stop you.
The real problem is that we have an entire useless generation that derives validation from the internet, and if you look for it, you can find validation for almost anything, no matter how inane. So instead of learning from the usual consequences of life and wising up accordingly, they recast poor choices as victimhood, portray their bad ideas and delusions as individuality, and use social media like a drug to fuel it.
In the past, people have tended to quit liking stupid shit when they reach their 30s and start having real responsibilities. Now a large number of them seem dedicated to dodging responsibility at all costs, and all they have learned how to do is throw tantrums and demand that some rich guy should take care of everything for them. An entire generation that basically does the equivalent of going around talking shit about their parents constantly, while also demanding that their parents pay for anything they want.
It's not that education is failing, it's that education doesn't do anything to fix it if you are just a miserable shithead.
