End The Federal Reserve. It is the most heinous criminal organization that has caused more human suffering, loss of life, and wasted toiling and effort than any organization that has ever existed in human history.
That would need to also end fractional reserve banking and abandon the Chicago school of economy and embrace the
Austrian school. The Austrians want gold as currency (not a fiat backed in gold or bank notes, but actual gold coins). But we now have Bitcoin, which is a good substitute.
Of course switching to the Austrian school mentality implies changing many (bad) habits, such as getting in debt rather than save to buy/invest.
In short, yes: just embrace the Austrian school. Teach about Ludwig von Mises, Friedrich Hayek, Huerta de Soto, and friends.
The question was about America, but its equally valid for All the World.
Of course, the bankers would not tolerate such a thing, which is why the status quo remains...
If banks were forced to play with full reserve rules, no national reserve would be needed, but they would shrink inevitably. Under those rules, you can still let them loan your money, but during the loan that money becomes unavailable to you. Also, if you don't allow it, logically you have to pay the bank to keep your money safe, not the other way around... Remember, with money that doesn't lose value overtime, the need for banks shrinks. Unfortunately gold is a bit too risky to keep around: Enter Bitcoin.
If you still have fears of deflation, you have yet to read the Austrians. Don't fear it, it works, and beautifully too; its simply slower to growth, but bubbles an crashes are no more. Read and recommend others to read Austrian economics, its free online:
