President Obama needs a lesson in Econ 101. Requiring that business meet a new fuel economy standard in order to achieve some environmental goal, no matter how discredited the theory, is one thing, but justifying it by claiming that business and consumers will benefit from lower prices is another. If this were the case, there would be no need for the new fuel economy standard either for big trucks or personal automobiles. Business pursuit of profits and consumer pursuit of better deals is all that is necessary. Let the public be warned: higher fuel economy standards for both big trucks and automobiles will cause our cost of living to rise and our standard of living to fall.
