> "So, why is it that America now has a paper-money system? It is undeniable that the Constitution has never been amended to abolish the gold coin/silver coin system and replace it with a paper-money system. Yet, it is also undeniable that despite the fact that the Constitution doesn’t vest the federal government with the power to issue paper money, it has been doing precisely that for almost 100 years. Moreover, it is also undeniable that although the Constitution prohibits the states from making anything but gold coins and silver coins legal tender, the states have been making paper money legal tender for that same length of time."
