I'm a big fan of questioning those in authority. Unfortunately, millennials only want to question those they don't agree with.
The lack of understanding of history is a big problem IMO. That includes using current morality in viewing historical events.
Here's how bad it is: I was talking with a 20ish coworker the other day about the new Mission Impossible movie (I haven't seen it yet). I mentioned that I grew up watching the TV series religiously every week, it was one of my favorites.
He gave me a stunned look, and blurted "it was a TV series?" No wonder Hollywood gets away with rebooting everything good from the 60s and 70s...lol.
Another young man and I were talking about the bitcoin market. I said, I'd love to invest in it, but I lost all my money in the Dutch Tulip craze (400 years ago). He had no idea what I was talking about. Yes, history does repeat itself, over and over and over...
Crap, I'm so old my battalion in Germany was deactivated some 25 years ago.
Half the "songs" used in today's commercials are 60's and 70's songs.
My millenial colleague tried to convince me to buy bitcoin in the $50's and I ignored. Finally bought a bunch from $350 to $400. Next time I will listen to the millenial.
