The retirement issue isn't just a Millineals problem. This article states that 37% of Gen X won't be able to retire as well, and nearly half worry that they'll run out of money.

Ignorance has dire consequences, and it seems that most Americans are ignorant. They say that knowledge is power. How many people are willing to take the time to read about investing? Or, how to make additional income? Or, read inspiring stories on people who have been able to go from being in debt to being able to retire in 5 years. Those stories exist.
But No!!! Why should I need to read when I can act like everything is hunky dory. I can just ignore the fact that I'm in debt so I can watch hours of Netflix, hang out with my friends at the bar, and/or play video games until the sun rises.
IMO, people are soft today. They don't want to put in the work. They'll do just enough and that's it. You can make all the excuses in the world. And, most of those excuses are valid. College debt is real. You might be $100k plus in debt. You might have difficulty finding work, or maybe you were abused as a kid. Those are real concerns. But, A) No one gives a f*k, and most importantly B) it doesn't solve anything.
Sounds like the head bump you took as a baby affected your reading among other things.
The link you quoted said "Gen Xers were derailed by three market downturns" - crashes of '87, 2000 and 2008 meltdown. And being the "first 401(k) generation," which transferred the responsibility to fund retirement from employers to workers". Hardly the irresponsible netflix and video game generation you are talking about.
Read about investing? Sounds like you think investing as a layperson is real easy and all it takes is "some reading" even with the stock market being very overvalued and volatile compared to how the previous generations had it.
Read inspiring stories from being in debt to being able to retire in 5 years? Probably money also grows on trees in your world.
