Every state posted GDP growth between 2000 and 2010, according to the latest U.S Department of Commerce data, which was released earlier this week. The growth rates, however, were very wide. Michigan’s GDP grew a little over 2%. Wyoming’s nearly doubled. This wide range reflects the extent to which GDP improvement is good fortune much more than it is due to government planning or industrial policy. Factories close because of the worldwide economic slowdown while inclement weather can destroy crops.
