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.
