Coolidge believed that promoting the interests of manufacturers was good for society as a whole, and he sought to reduce taxes and regulations on businesses while imposing tariffs to protect those interests against foreign competition. Coolidge demonstrated his disdain for regulation by appointing commissioners to the Federal Trade Commission (FTC) and the Interstate Commerce Commission who did little to restrict the activities of businesses under their jurisdiction. Under leadership of Chairman William E. Humphrey, a Coolidge appointee, the FTC largely stopped prosecuting anti-trust cases, allowing companies like Alcoa to dominate entire industries.
