On the one hand, yes, the job market *is* a bit down right now, and yes, getting a job, especially a decent one, has always been more difficult when you don't have any meaningful work experience yet.
But I don't think it's really significantly worse, at least here in the Midwest, than in past generations. The young people I know, generally have been able to find work that is commensurate with their qualifications, to an extent that is pretty comparable to what I've seen in the past, most of the time. Occasionally, somebody in a previous generation has gotten lucky and had an easier time and gotten snapped up for basically the first real job application they filled out, because the economy was up or whatever (my own experience getting an IT job in 2000 is an excellent example of this), but that has always been the exception rather than the rule. For most of history, getting your first really _good_ job has been difficult, and often required you to work a not-so-fantastic job for a few years first. (Heck, I worked fast food for several years, including a couple of years after getting my degree, before I lucked into that IT job. I've never regretted having that in my background, though I'm certainly pleased it didn't end up being my entire career.)
On the gripping hand, my experience with Gen Z is that in terms of employment opportunities, they aren't really any more entitled, on average, than Millennials were at the same age. Somewhat less so, if anything. If there's an aspect of their attitude that's worse, it's more social than professional and is related to how much they expect other people (especially casual acquaintances, like coworkers) to care about learning and accommodating all their personal idiosyncracies that aren't work-related. But this could be my Gen-X bias coming through: we were taught to only reveal personal stuff to people we're actually close to. We expected our phone numbers to be public knowledge, but we kept our personal feelings private. Gen Z is pretty much the reverse.
