Is there a revolution in American saving?

The personal saving rate spiked up to an unusually high level in 2008 and spring 2009, prompting many observers to suggest that the financial crisis has created a new thrift ethic, reversing decades of decline in U.S. saving to near zero. The depth of the recent financial and economic crisis has prompted many to believe that there has been a sea change in attitudes toward regulation, independence and personal responsibility and that a permanent rise in saving behavior has taken place. There are many reasons for personal saving to have surged recently, however, and most of them are very temporary, especially the Obama tax cut, so it is not likely that the personal saving rate will persist at a higher level. Betting on fundamental changes in behavior is a risky, dare we say foolish, business in the absence of more fundamental change in the economic environment or incentives
