I'm not sure if this is covered in the documentary, but I read something very interesting about planned obsolescence...or at least, lousy quality...from China. The cheap products which fail from China is a planned strategy, because China has no social security program for its massive poverty problem -- by some estimates, close to a billion citizens. The shift of the world to buying all things Chinese-made has allowed China to keep its economic engine running, because of the constant failures requiring repurchases and at least maintaining a source of income for workers. If the U.S. began building its own appliances again, for example, and/or electronics, it would be enough to tip China over the edge to disaster.
Another good example of (((planned obsolesce))) is mandatory cloud connectivity for something that doesn't need to be connected at all. Yet, at any time the manufacturer can decide, now is end of life for a product you supposedly own. And suddenly it's bricked, even though the hardware is fully functional.
