Forcing a level of quality would force a higher price point, which would price people out of access to the good. And no, "but the prices are still high" doesn't get you out of this jam. For as high as they are now, they would be even higher with quality guarantees.
So, if you want the "high quality" you're used to, that may mean spending more because you can afford to. And if you can't, then take solace in knowing that the product that's shitty to you is a new luxury to someone else.
