Fifth, the task of forming economic policy and putting it into practice is highly decentralized across states and regions. There really is not a single U.S. economy, but a collection of specialized regional economies—think of the entertainment complex in Hollywood or life sciences in Boston. Each region has its own industry clusters, with specialized skills and assets. Each state and region takes responsibility for competitiveness and addresses its own problems rather than waiting for the central government. This decentralization is arguably America's greatest hidden competitive strength.

Absolutely positively YES. Another great article from one of my heroes, Dr. Michael Porter of HBS.
