In the chapter on Contradiction and Conflict in Social Systems, Luhmann writes,
One must guard against the widespread error of thinking that destabilization as such is dysfunctional. Instead, complex systems require a high degree of instability to enable on-going reaction to themselves and their environment, and they must continually reproduce this instability–for example, in the form of prices that constantly change, laws that can be questioned and changed, or marriages that can lead to divorce. One cannot assume that everything remains just as it is but must constantly renew the security of information relating to the continuation or change of expectational structures. (367)
Nations such as China have decided against re/producing instability through elections or a division between government and opposition, but China does allow price instability. The leadership recognized that prices must fluctuate.
