As economists and stock reviewers will vouch, analysis can vary depending one's prism, or perspective -- i.e. how one views the economic world.

Look at the 2008 U.S. economy one way, and you see the onset of a conventional recession. Five or so years of GDP growth, earnings growth, investment, resource / commodity / raw material utilization, and consumption have basically run their course, and a pause is due. It's a period of lower earnings, less investment, lower consumption, and we call these pauses recessions.

Look at the 2008 U.S. economy another way and you see a different picture. Five or so years of GDP growth, earnings growth, but also substantial asset price inflation - - primarily in residential real estate - - combined with only modest improvement in the U.S. trade deficit, federal budget deficit, national savings rate, and a substantial weakening of the U.S. dollar. Then, a period of slower growth ensues, a slowdown made all the more onerous by the appearance of a credit crunch that began when the real estate balloon began to deflate, if not burst.
