It depends.
Certain hard to fill jobs will always be hard to fill as learning how to do it takes a lot of effort and most people are simply too lazy.
A friend's auto dealership had over 100 applications for an open administrative job paying $40k a year. Yet, the ASE certified auto mechanic positions, of which there were three each paying $80k a year, had no applicants.
Instrumentation electricians are paid upwards of $90k a year in the city I am going to school in but the vacant positions are hard to fill. The tech school is about 18 months, but no one wants to learn the math or crawl through confined spaces all day.
Hard work in hard industries requiring hard skills pays well, but few want to do the work.
Petroleum engineers start at $80k in the US and can make $110k in ten years or sometimes even more if you are willing to travel abroad. But only half the people starting the degree finish.
Enlist at 17 in the USAF and retire at 37 with $24k a year for life or go officer after college at 22 and retire at 42 with $45k a year for life and free medical care in either event.
None of these are likely to be replaced by robots anytime soon.
I could give many more examples.
If I were to mentor a young person I would say to watch a bunch of Mike Rowe videos and make your mind up from there.
The only exception would be for entrepreneur type people, but everyone knows who they are by the time they are 11 years old.
As the Happy Body guy says, "hard decisions, easy life....easy decisions, hard life."
