The education system is to blame.
Kids are conditioned to associate learning with a formal course with a tutor culminating in exams.
It's also intentional to segregate skills, if schools taught every child basic plumbing or car mechanics for example instead of spending a month teaching something that won't get used in life, there would be less job in those fields.
"I have never let my schooling interfere with my education."
So there's a conspiracy between plumbers, mechanics, and public schools to not teach basic handyman skills to the students?
We used to have "shop" (or similarly named) classes for this in junior high/middle school. They have mostly been cut, but more for budgetary reasons. A lot of high schools still have a vocational department for the kids who are not college-bound and not complete wasteoids.
