The issue is that several career tracks have some form of low pay, filtering, or outright hazing when you start out, with the promise that if you stick with the program, you will end your career at the top. Medicine, law, etc. If that promise is taken away, a lot of people on the job and in the education pipeline would be questioning whether it was worth the pain points (and not thinking about reforming and improving the entry level experience, lol). In the US this is one of the fears around socialized medicine.

Another problem is those career arcs are so long, where in something like tech or consulting, if you stick with it for 5-8 years you historically have a lot of seniority over new hires.
