He's saying the luxury of an existential crisis is a symptom of a bloated economy. In 2008, you'd be lucky to have a job at all, and very grateful if you did. As that memory fades, people feel more and more entitled to a comfortable existence. When they reach the level of "if i'm the least bit unhappy with my job, fuck it, I should quit and do something else"...we've jumped the shark. At least, that's my read of what he's saying.
True. Last year, I resigned and then started looking for a job and got several offers. This was only possible because all of my co-workers were able to find better opportunities. If it weren't for the good job scene around me, I probably wouldn't have resigned.
Yeah that's basically my point. I want to state, though, that I'm not just beating up on the under 30 crowd. I empathize with all struggles. But the same way that some people have never known a world without the internet, some people have never been hit by an economic recession. So, you have a lot of smart, ambitious people aged 24-32 who have built an impressive ~5 year career during a time of great economic expansion. For someone in this category, my advice is this: find someone 10 years older than you who works in your field, and ask them what their life was like from 2006-2010.
