don't let bias affect your view. china is better and better, check the women suicide number, check the coal mine death number. if only one really calms down and check all data.

but why people become more and more unsatisifed, it is easy, because we are evolving too with time, we become more and more "spoiled", we demand more and more, like the old saying " eat meat from bowl, then put down chopsticks and start" foulmouth, or as obama wondered "i don't understand why people are so angry" (talking about populism and trump supporters)

we human beings are greedier and greedier.
