Often those products do exist, but you need to become an “expert in X” to find them.
Oh… you want to buy a high quality leather [whatever], better start learning about leather grades, leather tanneries, stitching thread, stitching types… so it doesn’t blow out in a year.
Except we can’t all become experts in all products, and many companies are perfectly happy to build a brand on quality and then slowly erode that quality to increase margins.
