William Howard Taft,
Hampton Company v. United States…
“ The title of the Tariff Act of 1922 (42 Stat. 858) , of which section 315 is a part, is 'An act to provide revenue, to regulate commerce with foreign countries, to encourage the industries of the United States, and for other purposes.' Whatever we may think of the wisdom of a protection policy, we cannot hold it unconstitutional.So long as the motive of Congress and the effect of its legislative action are to secure revenue for the benefit of the general government, the existence of other motives in the selection of the subjects of taxes cannot invalidate congressional action. ”
