I'm not surprised in the least. Think about it. You have a country chock full of people, with little natural resources to draw upon. Korea has no particularly outstanding exports. So, it seems logical to me that it would focus on developing its service based industries and the end result is that people are more educated and can better utilize technology. Furthermore, you have an education system that promotes fierce competition between students who are not geographically spread out. On top of that, you have almost complete globalization of knowledge with the boom of the internet. Anyone who's posted in tech support from Utah, and gotten a solution from a nerd in Jersey knows what I'm talking about here.
In this country, we have the exact opposite situation. We have lots of resources, lots of people, lots of land to cover. There isn't a pressing need to push technology either, as it was in Korea. Taking this into acct, we are also a country that has this terrible tendency to repeatedly hinder technological advance. I could go on for hours about this one thing alone...but suffice it to say, I'm not surprised in the least.
