Yep, I remember being told that it doesn't matter which major I pick because there would be jobs that wanted just any bachelor's degree.
I'm sure high school kids are still being told that today, and it might not be entirely false. Decent-paying jobs have certainly become more specialized for specific college majors, but I still see local job listings on the lower end of the white collar pay scale that ask for a BA/BS without expressing preference for a specific major.
When only the self-selecting intelligent/diligent/driven went to college, selecting college graduates was a huge win.
So then everyone decided everyone should go to college - to me that's manifestly not the case, but that's where we are; plumbers doing quite successfully for themselves with a degree in something or other that doesn't matter at all.
