The caste system, much like slavery, is a strong deterrent against industrializing.If not for the absolute anarchy happening in India during the 1600’s, I’d have put good money on them industrializing first.
When people say eurasia, I think they mean britain, to morocco, to saudi arabia, to thailand, to japan. Is that a wrong assumption?I'm not sure that the OP is true; for that matter, historically Eurasia has not always been at the "top" to begin with. In ancient and Medieval times, other regions such as Arabia and China were at times ahead of the Europeans culturally and technologically.
