Tariffs Tariffs were used to fund the United States government prior to the imposition of the permanent income tax mainly because it did not cost so much to run the federal government: there were fewer expenses in terms of funding social services, such as Medicare, Social Security or other unemployment.

This was the case under President Andrew Jackson, who proclaimed:

This Act was repealed, however, in due time.

Massachusetts Representative Samuel McCall stated that “the chief purpose of the tax is not financial, but social. It is not primarily to raise money for the state, but to regulate the citizen and to regenerate the moral nature of man. The individual citizen will be called on to lay bare the inner-most recesses of his soul in affidavits, and with the aid of the Federal inspector, who will supervise his books and papers and business secrets, he may be made to be good, according the notions of virtue at the…
