Here in Mexico there are plenty of "unofficial" laptops/mobile (Apple, Windows, Androids) repair shops that even receive your device by DHL/UPS, fix it and return it. Because the labor costs are low enough to make it worth. The only downside is that most of the spare parts are imported from the US.
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.
Difficult to determine causality in that system. All we can say is places with expensive labour tend to have expensive real estate. (The confounding variable, I imagine, is immigration.)
