Yes, the reason is the image problem in the eyes of customers. China will make anything to the manufacturer's spec and quality. Problem is that most manufacturers use China to cut their manufacturing costs drastically and also lower the quality. As Paul said, the customer has an image that products made in USA or Britain are perceived to be better quality than those made in China, which may not be true. Is there any evidence that Levi's made in USA is of better quality than those made in China? The higher price is due to labour costs in the US.Have you ever heard a salesman say 'this is the coveted made in China version. Much better than the USA/UK/Japan/Taiwan version!' Of course not lol. And there's a good reason for that.
You are unfortunately a minority. Buying second hand stuff supports no manufacturer and encourages no one to build high quality products or those that can be repaired. Apple has seen that if its products are repairable easily, you're holding on to their MacBook for 8 years and not buying anymore of their products. Pioneer would not have stopped making TVs if customers gave fair share to custom quality products. Kuro was the best TV at the time, leagues ahead than anything else out there. But they were losing money on every TV they sold, trying to find buyers buried in the sea of cheaply made TVs. It's us who have encouraged manufacturers to go cheap which spawned a throwaway society.
If you really want to reverse this, the only way is to buy well engineered products brand new and sell them on within couple of years to buy more of them brand new. Otherwise, good quality products will cease to be made. Or change the mindset of a throwaway society and have repair facilities which are easily accessible.
I still remember in 2004, I bought a bag from Argos for £6.04. the buckle broke within a month. So I went to a local repair shop who quoted £10 to replace the buckle! I was shocked; he said that's how it is now. It's cheaper to buy a new product than repair it. I went back to Argos to swap for a new one. Without doubt, the perfectly good bag with a broken buckle would've gone to landfill.
