Russ,
Re: Why gold?
Gold acts a store of value like many other thing, such as dollars, credit cards, bank accounts, baseball cards, clams, stock certificates, etc. When the world's artificial fiat money systems work well and economies run efficiently, gold loses it value. In these times, its only basic use is jewelry. It cannot grow, cannot be used as food, and cannot be used in industrial processes.
However, when these political economic systems collapse, gold rises in value due to its perceived inherent value.
For the past 20 years, we have had an economic expansion (bull market since '82). Gold has decreased in value. For the latter part of the last decade, we have had an artificially induced boon created by artificially low interest rates mandated by central bankers. The result is excess credit which inevitably leads to excess debt. In our case, massively excess debt. The bubble is slowly deflating and central bankers are now only exacerbating and delaying the inevitable. What will happen is a rise in gold.
And along with gold, so will other commodities rise. In an artifically induced economic expansion, money flows to "hot" industries like dotcoms, semiconductors, and telecom equipment. Basic things like commodities (gold, oil, platinum, food, coal, lumber, etc) are ignored until they are massively undersupplied. Also, because of economic expansion, their demand rises, but nobody cares since all the new investment is happening in "hot" industries. At some point, this cycle breaks and commodity prices skyrocket. Some signs of this are already evident - oil prices bottomed in 1998 and have tripled. Platinum has just about quadrupled in the past couple of years. Natural gas prices have increased 10-fold in the last 2 years. California has not built any new plants in over 10 years and now the price of power has dramatically increased.
Sooner rather than later, the rest of the commodities will rise in price, including gold. I believe we are on the verge of a new bull market in gold. I think that other commodities are better values because they have more industrial uses. But gold is about to have it day.
