In Western countries, the time of skilled repairmen is better spent repairing things which are much more important and expensive than consumer goods.

And a consumer usually has a much higher return from working in his specialized field to earn money and buy a new product, than spending time with difficult repairs of a broken product.

Yeah, this is entirely a function of labor costs. If you want your stuff repaired, ship it to a low-labor cost economy or hire someone to whom it’s worth the time.
