I guess I could have expanded on my last sentence more and completed the thought. Of course nobody wants to be the person who works the drive through at McDonald's as their life's ambition. This type of job used to be seen as a stepping stone that provided you some spending money and an opportunity to meet people outside your parents social circle and school, a first taste of the working world, but wasn't a determinant of what your career ended up being. Gen Z though sees people /their age/ every day online who have become multi-millionaires on the Internet by being social media influencers or content creators, and they want to jump straight to the end where they're famous, rich, and respected (arguably).
My generation was never exposed to that, we were exposed to Tommy the lawyer who got his start working the stock room at the hardware store and now drives a Porsche. The type of "instant" fame and money that kids get exposed to now just wasn't even in the realm of possibility for my generation, except perhaps sports stars. Even though the number of people who "make it" vs those who try is vanishingly small, a lot of folks in Gen Z seem to think being an influencer or a similar role is the primary career path they want to try for, and unlike something like being a sports star, it's less limited by outside influences and requires less genetic talent. Anyone could, possibly, be an influencer, even though very few people actually will become one.
Now, taking that job is no longer seen as a stepping stone, it's seen as giving up and admitting to yourself and the world you won't be able to hack it online. It's truly remarkable if you observe high schoolers, girls especially, these days and how much of their life is spent online vs with those directly around them. Social media is not just entertainment, it's one of the most important things in their lives, and their presence there is seen as a determinant for their future. This is a very different social zeitgeist than my generation grew up with, and I'm a Millennial, grew up with Internet and computers, but prior to the dawn of social media.
This isn't an economic issue in that sense, then, it's a social issue, a rejection of the type of work that most people in the US started with when they were that age. A drive through worker at McDonald's makes nearly $37k/yr if they work full-time at the starting wage where I reside now. That's more than many professionals made when they started their careers when I was a teenager, and it's more than double what I made starting as a shelf-stocker /inflation-adjusted/. It's not that the job doesn't pay enough to attract people who are starting out, it's that those people see it as a serious social faux pas to be caught working that type of job, it's an admission and acceptance of failure, rather than an admirable place to begin.
