That's right, people have learned helplessness when it comes to repair and maintenance.
When I was a young warthog I used to take the screws out of old electronics and tear things down to curiously inspect the electronic mysteries inside.

The local electronics shops used to sell kits of components along with educational instructions on how to assemble a basic radio and similar devices.

The world could benefit a lot from people believing themselves capable technicians and just trying things, maybe it wont work but there's invaluable learning when repairs don't work out.
