If so, there should be policy support/subsidy to help train those who wish to shift to these options which, to my knowledge, pay pretty well and will continue to be in demand for the foreseeable future (little automation is likely, given the limits of current technology.)
That's the problem with most difficult to automate jobs that don't require college degree. They sound like anybody could do it. But there is huge difference between good renovation and bad renovation. The kind of guy who can do good job consistently is rare. The job requires passion and good attitude and personality that matches the job.
It's kinda sad how many men are passionate about driving a car. It's bit like how many women used to be passionate about weaving.
Artisan carpenters/master technicians would still be in high demand but those transitioned to the new careers would serve a different market and needs.
