From the Wiki entry: > when a country has reached an economic development where it has a middle class strong enough to support a McDonald's network, it would become a "McDonald's country", and will not be interested in fighting wars anymore It's amazing how persistent this basic idea is. "Once we reach a certain level of X, we won't fight wars anymore." X can be money, education, scale of war (WWI), etc. but the idea never proves true in the long run. Nations fight for the same reasons toddlers do, just at a much bigger scale and with far greater consequences.
