I'd have to go back and watch it to be sure, but I remember a lecture on Social With Chinese Characteristics that mentioned looking back on their history and drawing from from ancient/dynastic literature that wished for prosperity for common people (then the peasants) and that was the sign that the country and ruler was good.

So SWCC was synthesized with this part of Ancient China and the result today seems that part of the historical identity of modern China is about striving for prosperity for your fellow workers.
