You get slammed for people not liking your response, but yet your point is spot on. The number of vegetarians has been pretty steady over the last decades in the US. Hoping people become all vegetarien isn't practical. If I was a dictator I'd ban meat eating, but I am not and that's good.
As always: it's not allowed to ask for better people! We need to create a system that makes the wrong people do the right thing.
I think this is precisely it. We all (many?) of us expect ourselves to have an extraordinary life and then we inevitably end up with something more ordinary than expected.
I do wonder though if there is an additional component for folks in tech careers. If you stay heavily invested in the technology aspect of it, you might start wondering how much longer you can keep up with you folks in learning about the latest technology. If you move to the management track, you might feel less secure about your job and your ability to get a new position, especially as your former strong suit, the tech knowledge, atrophies. I moved to the manager track and sometimes interview folks for manager positions who are 10-15 years older than me and have been struggling to find a job for a very long time. Their tech skills are entirely outdated and I ask myself if that's me in 10 years.
