America was relatively tax-free in its early days. In 1862 the first income tax was levied to pay for the Civil War. In 1895, the U.S. Supreme Court ruled that an income tax was unconstitutional. In 1913, however, the same year the Federal Reserve System was created, the Sixteenth Amendment was passed, making an income tax permanent. The reason for the reinstatement of the income tax was to capitalize the U.S. Treasury and Federal Reserve. Now the rich could put their hands in our pockets via taxes permanently.
