An article that will help you understand gold is Gold and Economic Freedom by none other than Alan Greenspan, former chaiman of the Federal Reserve Bank. It is contained in Ayn Rand’s book Capitalism: The Unknown Ideal. The rest of the book is worthwhile too.
Inflation is money devaluation. The value of anything is dependent upon its supply and demand. Something in low supply, and likewise low in demand will not have a high value. Likewise with something in high supply, and high demand. Something in high supply and low demand will have very low value. The money maker is something in low supply, and high demand. The man with his hands on that supply will reap great wealth.
Any material goods we may possess represents our labor. We work to obtain material goods, food, clothing, housing, etc. Metal coins represent labor. It takes labor to dig the metal from the ground, purify it, and stamp it into a specific size coin. When money becomes scarce because of the greater amount of goods available on the market, then prices go down, and the metal’s trade value becomes high. This will prompt some to go searching and digging for these metals again to perhaps strike it rich. As the metals are found and minted into coins, and more money reaches the marketplace prices will begin to rise. When it gets to the point that the labor in finding and digging the metals exceeds that of other occupations to provide a livable wage, the supply of metals will decline. If the manufacturing, and production of goods continues to incease, it will prompt a new search for metals to coin.
Currency, or paper money is a bit of a different animal. Paper money used to be warehouse receipts. The paper had written on it the item stored, and the place of store. One size of paper could represent a peanut, or a peanut farm. A one hundred dollar silver certificate could be printed on the same size piece of paper as a one dollar silver certificate. You however cannot take two coins of the same metal and stamp a “1” on one, and “100” on the other. Originally Federal Reserve Notes, 1914, and 1934 series were redeemable in lawful money. In other words you could take them to a bank and get metal coins for them. The banks were the warehouse, and certificates, and bank notes were the receipts.
Certificates are no longer in circulation. Federal Reserve Notes are no longer redeemable in lawful money. In fact they are not redeemable in anything. Our money is a paper standard. In that case a $5 note should be five times the size of a $1, and the $100, one hundred times the size. Of course a $100 note would be like having one hundred $1 notes. You would want to let that stay in the bank, and get a receipt for it, which you could carry around much easier. This is the reason the certificates became popular. One hundred silver dollars is not a light or small load. One hundred double eagle gold coins would be a bit smaller, but not any lighter, and would have the equivalent value of two thousand silver dollars.
Printing money with nothing to constrain the amount in circulation except the speed of the printing press, and the amonut the bank is willing to lend, there is no natural balancing force between the items used as a medium of exchange, and the amount of goods available in the marketplace.
The U.S. Dollar is in such great supply in relation to the goods in the marketplace, so prices go up. Part of this is due to war. Wages are paid to produce military goods which are not available in the marketplace, but the wages are spent in the marketplace. We no longer manufacture much of anything to export, and therefore import a great quantity of goods. When the supply of U.S. Dollars in the marketplace decreases enough, the foreign exporters loan our money back, by such negotiable papers as treasury bonds, so we can buy goods from them again. When these countries start swimming in U.S. Dollars because we do not produce something they need, they are not going to want them anymore, and want to exchange them for something. The only thing we have is businesses and land to trade to get that money back, so we can buy more goods from them.
Immediately after the September 11, 2001 disaster the Fed pumped $50,000,000,000 into the economy. They did not drop it from planes over the country. No, it was loaned to the government. The present wars are kept in progress by continuous loans from the Federal Reserve Bank, pumping more money in the marketplace without an equivalent increase of goods resulting in the decreased value of the U.S. Dollar, i.e., Federal Reserve Note, and therefore an increase in the amount of dollars to buy the same goods.
