I think the key here is “at their jobs and careers”. New generations just don’t see their careers as the center of their livelihood. Their goals have nothing to do with climbing the ladder. It’s not a victim mentality to just refuse to participate in a rigged game, especially when there are other games to play. A job is a thing you do so you can live, that’s it.
In my opinion (dont take this personally), I think it is a victim mentality, that if someone self sabotages enough, someone else will fix things or improve their situation.
I think a closer model of reality is that most people are disposable. I dont think that people becoming more disposable less important increases leverage.
A lot of historic change has come from organized striking, but only when the strikers have coherent demands and productivity to leverage.
