the 'work/boss is evil' sentiments are as expected prevalent here. And because I was lucky to have a career that was reasonably satisfying, it just got old after 35 years plus #4 below. I understand and can argue both POVs.
May seem somewhat uncharacteristic for me, but here's a good article that seems to provide a broad list of reasons most people really don't like their work and don't see much future in it. Though it's written for folks who haven't yet retired, the themes will probably be familiar to all adults.
It also points to what it's going to take in the future, nothing new there. FWIW...
