I think school system is hugely failing students if they are not instructed and then capable of spending one or two afternoons on simply googling and looking at career prospects and what different jobs actually might entail. And then at least with minimal criticality thinking is that for them.
I am pretty sure there is no careers you cannot find some information on with rather simple searches.
This belief that "a degree, any degree" is sufficient must have started after I went to University (mid-90s), because when I was a teenager, it was drilled into us that we need to not only go to University, but we need to major in something lucrative. Nobody, from parents to guidance counsellors, was saying "Oh, just go to college and major in anything, it doesn't matter!"
