China is turning out so many EV cars, dealers are buying back old one's to keep the price up. This is what BMW did (and possibly other German car manufacturers), in the late 80's/90's. Another thing I see China doing, is pegging their currency to the dollar, now when the UK did this to the stronger German Deutsche Mark, the UK under Lord Norman Lamont crashed out of the Exchange Rate Mechanism and the UK saw interest rates hit 12/13% so I wonder if this chip shortage has more to it other than investment reasons only?
