I wonder if that's actually a good idea. The best time to start learning a skill/trade (includes white collar stuff) seems to be when it's not YET in demand. For example, the worst time to start learning software development was at its covid peak in 2018/2019. If trades are going to be in huge demand now, a lot of people will start learning them and in 5 years of so we're back to square one with low pay and huge competition.

Then again it still probably is more useful than bachelor in hr. Trades are awesome "emergency" / "economy downturn" skills to have.
