That, to me, sounds like an argument for funding trade schools and raising their status in society so they're considered more often. As I understand it, a university education was never intended to be a gateway to employment, yet it became one as a byproduct of how we as a society talked about it. I was told countless times in adolescence how much of an income gap existed between those with a college degree and those that didn't have one.
Software development, for example, very much falls under a trade, else there wouldn't be so many bootcamps that both feed into the industry and simultaneously take advantage of those who don't know better. There's no prestigious trade school that I'm aware of that produces consistently competent software developers. That's just one example, but I'd love to see more trade schools supported and elevated as a path to career employment.
