Message:: [QUOTE="Just Carl, post: 232064, member: 4552"]Another thing to consider is the prices of metals. As our scientific community surges ahead with materials that are not metalic in nature, eventually what we now consider expensive metals will drop in value due to lack of usage. Most dentist have stopped using metals for teeth. Most communication systems are either Fiber Optic or wireless eliminating millions of tons of wires that used to be used for this purpose. When was the last time you saw a car made completely of metals. I have a car that weighs over 6,000 dry weight but that was made in 67. That is now the weight of several cars made of plastics. Most piping in houses today are plastic, not copper or steel. Many areas use premade wiring where conduits are not required. When you hear about the price of making coins being so high note the government is not complaining. It's only the tax payers that complain and the Mint goes on and on and on. It will not be long before some kid says "Hey Dad. What is that stuff I heard on TV that was used in the old days called MONEY?"[/QUOTE]
