Well I think that the United States will simply be eclipsed on the world stage if it does not develop more mega-cities. However, I am not saying that we should promote massive growth of concentrated centers without addressing the social, psy, and enviro impact! Because the purpose of a great city is not to build buildings but to create the best conditions for people to cooperate and concentrate their efforts. Also, I am not saying that a place like San Fran has to or even should make the sacrifice. Because going big is a huge sacrifice that destroys a lot of wonderful things. So, as a former resident of LA: "I choose Los Angeles to be sacrificed for the betterment of the nation" LOL.
