Suppose the United States gives a subsidy equal to 30 percent of the purchase price for people who buy imported goods. It also taxes all goods that are exported from the United States by 30 percent. This subsidy and tariff regime would likely have a substantial effect on international competitiveness.

The Washington Post does not see it that way. A front page article that discussed the production of energy efficient light bulbs, and the factors determining plant location, did not once mention currency values.

This reflects an incredible level of incompetence. It would be like discussing the Louisiana fishing industry without discussing the BP oil spill.
