I believe that banking institutions are more dangerous to our liberties than standing armies.

Jefferson best explains this himself:

If the American people ever allow private banks to control the issue of their currency, first by inflation, then by deflation, the banks and corporations that will grow up around(these banks) will deprive the people of all property until their children wake up homeless on the continent their fathers conquered. […] The issuing power of currency shall be taken from the banks and restored to the people, to whom it properly belongs.
