One of the obvious examples is "build in failures". Remember when your device became useless just after the warranty expired? Well...

I completely agree with this statement including many others you mentioned in your post. If everything had lasted forever, the companies would not had lasted for too long, they would go bankrupt without liquidity and also most humans in developed countries are used to new things, so if anything lasts for too long, even though it’s still perfectly working, they just throw it out anyway and buy a new one. I personally prefer quality. However,if I were as a salesperson, I would prefer customers going for quantity and getting new product every one or two years. Let’s be honest, that’s the way the human brain works.
