Can Federal Legislation Affecting Consumers' Economic Interests Be Enacted?

Assume there is a definite need for legislation which centers on the economic-not the health or safety-interests of consumers. Can such a bill be enacted? If history, as Francis Bacon claims, does indeed "make a man wise," then a wise man would not even advocate such a bill, no matter how persuasive the evidence. Although government exists to protect the public interest, a look at history shows that the public--or the consumer-generally has not fared as well as many other special interests.
