Boomers in the 80s and 90s were fucking depressed. They described their lives as a boring, soul-crushing existence where they did the same hollow shit day in and day out. They hated their bosses, they hated their jobs, their kids, their wife/husband. People had "Mid-life crises" where they tried to fill the void with "a fast car and a young hot fling." things capitalism told them would make them happy. It didn't.
Seriously listen to any media made by boomers when they were in their 30s-50s. It's all jokes about how fucking mundane life is.
Even at its peak, life under capitalism was hollow and soul crushing.
They were basically taught "as long as you keep your head down and play the game, we won't hurt you financially"
Sure, (if you were white and male) you had money, but it took everything else away. Community, friendship, family. Trapped them in a gilded cage. Having to watch their children having even that promise of financial stability ripped from them. And don't get me started on how terrible it was if you weren't a white dude.
I have to wonder if the "selfish, childish boomer" stereotype is something of a coping mechanism. Maybe some boomers are like that because thats their jokerfication.
I am old enough to remember boomers making an entire media era about wailing for their receding hairlines and gradual awareness of mortal limits. That era fucking sucked and it was full of sex pest shit like creeping on teenagers as a normalized practice. City Slickers the film is like a period piece summarizing that mentality.
