The guy in the first video posits that China will Have a more successful economy than the US in the future because as a command/control driven market economy it can move quickly to respond to market needs without the limitations a democracy places on leaders. (I'm paraphrasing). The problem, as I see it, is that efficiency losses will occur. Inevitably China's leaders will trip up and interfere with the economy. A central government can easily order financial institutions to support stock prices but their is a cost and limitations on how that can work. China is competing on the basis of low wages and few environmental or health/safety regulations. That does not bode well in the long run.
