It's interesting you should say that. There are a number of sociologists who have commented on the similarity between Asian (and more specifically Confucian) cultures and Southern culture.
I have heard similar observations from one of my history professors, Dr. Lung-Kee Sun. He is also a fairly astute observer of the details of such things.
Interesting about that comparison between the South and Confucianism.
Dedication to family and country.
A love of order, hard work, and fairness.
A preference for moral straightness--with the understanding that not everyone falls there all the time.
Sounds like a lot of the folks I hang out with in parts East.
