No doubt the population, economy and human rights are among the highlights.
Some of these may not be so unbelievable; I mean, it’s no secret that China’s policy on human rights is non-existent. Lower-class citizens are treated more like mechanical bits than they are like human beings, and when the mechanical bits aren’t functioning up to standard, the government doesn’t think twice about getting rid of them.
One thing I think people are beginning to notice is that any downfall of China will be caused from within the country, not from its surrounding competition (as has usually been the case). An unsatisfied population in an economically prosperous country doesn’t stay quiet for long: this is just a fact of history.
