Top 10 most imporant cities in the U.S.

My opinion on the top 10 major cities in terms of importance are, New York City Washington D.C. Los Angeles Chicago San Francisco Boston Atlanta(And no I'm not saying that because I live here, because of all the major companies that function around the world). Houston Philadelphia Dallas This doesn't mean they are definitely the top 10 but those are just my opinion. From what I've seen that the city posesses, I base it on that.>
