Market Dynamics
Pull out your old economics textbook and read the chapter on monopoly power. China undercut prices to close the molycorp mine. Now that the Chinese are exercising their monopoly power, it is backfiring on them. This is what happens when critical strategic resources are outsourced to other countries, especially communists. China is one gigantic national monopoly. They do not have a true market economy. Their version of communism looks a lot like US capitalism during the period 1850-1970. The only difference is they owe us a great debt for saving them from total Japanese enslavement during WWII.
