I feel like all of these "us vs them articles" (us = millennials, which I am one, and them = baby boomers, who are my parents age) are red herrings.
Do you really believe that your mother/grandmother is the enemy here? My belief is that who you're actually imagining when you read this article is some fat-cat corporate executive in a suit and tie who is old enough to reap the largess of Reagonomics. They happen to be 60+, but in actuality, the distinguishing feature is that they're rich.
My dad is a retired firefighter and Vietnam vet, and my mom is a executive admin. These are two people who should not be blamed for the cards the youth have been dealt.
It's the Elite. The Controlling Class. Whatever you want to call it, they enacted policies some decades ago to benefit only them, and now they're reaping those rewards at a staggering pace. And they're quite happy that you have found someone else to blame besides them.
Even the "Top 1% vs Us 99%ers" is the same kind of thing. They're happy your anger is centered at plastic surgeons and defense attorneys. The real wealth is in the 0.01%, the people who don't have to work (and haven't for generations) and want to keep it that way.
As long as you are blaming someone else, they're safe and happy to keep pulling the strings on society. But I'm not going to take a cop-out excuse of blaming the grandmother down the street who has been living in the same 1800 sq ft home she bought with her husband and 3 kids in the 70s and hasn't ever update the decor in her kitchen.
