No. Regardless of how disposable you and manufacturers think electronics are, some people save and use their hard earned money to buy these things (as opposed to charging it and carrying a balance by only paying the minimum/interest or 0% financing gimmicks). Though, I think a mandatory warranty law just raises prices to cover replacement parts/repair, instead of actually increasing the product's build quality.
I used the warranty for a cheap mouse/kb from Logitech, and my G9x. I had an HP laptop with the overheating nvidia chipset that affected more than just me, it was repaired out of warranty but someone had to be sued first.
The U.S. economy would collapse for sure if everything didn't fail so easily and spending lowered, since all our stuff is made in China.
He who steps on others to reach the top has good balance.
