Doesn't matter because U.S. ruling class doesn't agree.
College is still a gate for higher paid trades because advanced manufacturing wants educated workers that can do math and/or programming g-code and/or know advanced metallurgy
I know someone who went to welding school, and he was basically practice welding 40 hours a week after class because he was working on some very advanced welds that actually required some decent chunk of engineering knowledge
Edit: can't reply below, but all of those vocations listed are offered at community colleges now and linked with an AS/AAS degree, as apprenticeships are often coordinated with CCs.
