I don't think it's entirely true. Students are told, over and over, to follow their passions. They're inspired by charismatic teachers. They pick up weird ideas about which fields will have good career prospects. Parents who "push" more employable options, are ignored. Having two college-age kids, and knowing many more, all I can figure out is that it's utterly a crap shoot.
Also, nobody at the high school level has any idea what CS is. I had a bit of a leg up (in 1982) because my mom had taken a bunch of CS courses, and was teaching programming at a nearby community college. But she thought I'd be better off studying a traditional field. I chose math, and taught myself to program.
I'd say yes and no. For instance I'm a parent, and I'm also involved in hiring tech workers, so I'm aware of what's in demand. I'm not that old.
When I started college in 1982, I'd argue that nobody knew. For instance, at that time my parents were also mid-career in STEM. Well, my mom was teaching programming at a community college, and her students were getting jobs after 1 year of her course. Based on where we lived, near Detroit, most of them were getting hired up by the car companies.
But I don't believe anybody knew what was going to happen next. My mom thought that programmin was too easy to spend time learning at the college level, and that the market for programmers would soon be flooded. What happened next was the personal computer. I was keenly interested, but at my college, the CS majors used a mainframe computer. Most expected to work for banks, insurance companies, utilities, etc.
Non-STEM parents, sure. I'll grant you that. I'm lucky to have been raised by two scientists. But they weren't thinking about money when they talked to me about careers and college majors.
