Heaven help us :)
The only reason we haven't seen 85% of society give up all at once is that some people still hold out hope that the BoomerJobs, once vacated, will be given to them. That isn't going to happen, though.
People work "hard" in our society, because they have no other choice, since there is no social safety net and employers can do whatever they want in this country, but no one really cares anymore. This has manifested itself as survivable mediocrity for quite a while, but as soon as our society finds itself in any kind of serious crisis it will collapse. It almost did, during COVID.
Yes, boomers had better pay where a middle class blue collar job could afford you a nice house and kids in the suburbs, but this idea you quote, I'd need much more data on because the entire culture of being a boomer is much more top down, listen to your boss, do what your told then the modern culture.
My experience of Boomers (my parents and their friends are early Boomers) is that most of them were working as two-income families, whereas my granparents' generation (late Greatest and early Silent), it was much more common for there to be only one outside income coming into the household.
