Big cities contribute to the economy, but rural states have undue influence in the Senate

I quote from the Pew Research Center report:

Reddit user Alexandr Trubetskoy based this map on metro-area GDP estimates by consulting firm IHS Global Insight (in a report prepared for the U.S. Conference of Mayors). Six metro areas — New York, Los Angeles, Chicago, Washington D.C., Dallas and Houston — account for almost a quarter of the nation’s $16.8 trillion economy; add in the next 17 highest-ranked metros, and you account for about half of all economic activity.
