My friends who got into welding mostly did so through aprenticeships with unions or on the job non union apprenticeships.
They will probably not become millionaires selling their time as welders but they are solidly middle if not upper middle class. They go on international vacations and eat at fancy restraunts. They are fairing on average far better than my friends with "soft" liberal arts degrees.
Yeah it's not a total panacea easy road to riches but learning a trade like welding seems like a super high EV move for a lot of people who want a stable career right now.
