In an unstable economy that continues on the downward spiral of inflation from the rampant printing of money, there seem little that a person can do to protect those assets already amassed. The way the Federal Reserve orders the printing of money is sending the United States along such a spiral; what then is a person to do in the face of such impending inflation. One dollar today will be worth seventy-five cents tomorrow and less than fifty in a year's time if the process continues. Unfortunately, wages do not follow suit until hyper-inflation takes over, so in the mean time, one needs to find a way to maintain the asset that cash used to offer.
Silver and gold have an advantage over the paper money we have today. The main advantage is that they keep their value because they are worth something in and of themselves. Gold has value for making jewelry (as well as some other things), and silver has value in much more areas than does gold. In 1940, a silver dollar (one ounce) could buy you 5 gallons of gas, and it would take the average person a bit more than an hour to earn that silver dollar. Today, 70 years later, one ounce of silver is around $22-$24, and the average person would take the average person a bit more than an hour to earn that silver dollar that would buy that same 5 gallons of gasoline. Not much has changed when it comes to silver. The price of gas has risen from $0.20 per gallon to more than $3.50 and even $4.00 per gallon in some places of the US.
If you want to protect your earnings from being wasted, which is a very frugal thing to do, then you should consider placing some of your money in silver and gold to act as a hedge against inflation. The number of people that are currently touting gold as the metal of preference have really not taken the time to research the matter very well. Not only is gold much more expensive than silver, but silver has outperformed gold as a hedge against inflation for more than 600 years.
Silver and gold have been used as methods of payment for a very long time. Records show that the silver denarius of the Roman empire was roughly an ounce, a bit lighter to be sure, but close enough for a good comparison. The average Roman citizen could earn 1 denarius per hour. So you can see that not much has changed since the Roman empire was in charge of the world.
Truth be told, the things that caused the collapse of the Roman empire are still running amok today in the United States. It would seem our leaders are intent upon repeating the same mistakes that ancient Rome made, including the rampant inflation of their currency. To offset your risk of losing your purchasing power (as well as a waste of your time at work) you should try to find something like silver to keep your savings from dwindling in the sight of the runaway printing presses.
Frugality is about preserving instead of wasting, you should take the time to preserve the wealth you have accumulated over the years instead of letting the Federal Reserve's printing presses waste all of your hard work. Worst case scenario, you end up with a few stacks of nice coins that can be passed on as a family heirloom. They won't lose their value, they seemed to have held up pretty well over the last couple of millennia.
