I think you discount the magic of the Christian faith
Did I come across that way? I did not mean it that way.
I suppose that I should consider more before I post.
1) Demographics will hinder China. The one child policy they have had for the last 40 or so years will leave them with one person supporting 2 elderly parents for a long time.
2)The fact that only the people on the coastal cities are anywhere near the poverty line is another.
3) The Han Chinese actively ruling over all the other dirt poor ethnicities and the resentment that breeds is yet another.
China is a long way from world domination (IMHO).
It was a unified pagan empire with a common currency, language and safe, efficient transportation and roads that let the “magic” happen, as well as a favorable latitude.
