There is a lot of room for cutting corner in manufacturing and it all translates to quality and consistency. My brother in law has a law firm and he happen to work with two different car manufacturing brands. He was explaining how two brands choose the glue differently to build the same part of their products. While for the Chinese brand it was only important that the glue has the minimum standard to be used in their production line, the Japanese brand was very specific about which exact glue from two particular brands can be used there. Which both happen to be more expensive than similar products with same standard on paper. But Japanese would only use that particular product because they did all their quality and durability tests with that.
