The article is pretty good but being the Economist (a staunch advocate for the war in Iraq), it is biased towards the Anglo-American capitalist system where money is the main motivator. It didn't explore, at all, how the sacrifices that were made allowed the country to go from complete devastation after the war (all major cities were suffered extensive destruction) to the world's 2nd largest economy in just 50 years. The motivator for that was not personal greed which is ultimately what Anglo-American capitalism is all about. There is something that is good and noble about being loyal to the group.

(BTW, I'm still trying to figure out whether greed is good or bad and haven't reached a conclusion. It seems to be the best way to allocate resources efficiently. But still....)
