The Washington Post June 28, 2012 In his June 25 op-ed column, "Why the economy flounders," Robert J. Samuelson's otherwise insightful analysis of the simultaneous failure of the economic models of the United States, China and Europe was seriously flawed by the omission of an important potential remedy. Mr. Samuelson said that the U.S. consumption model can be replaced by higher exports, more business investment and/or higher government spending. In fact, fewer imports are what is needed.More exports are useless in the face of more rapidly rising imports. Fewer imports would stimulate business investment and obviate the need for more government spending.
