Gold fundamentals

Lots of folks look into gold trades, some buy it as long term investment for collapse of US economy. I have never followed gold in any fashion, recently heard someone comment that it is useless to do so for the following reason. We spend lots of money to get gold out of the ground, ship it, buy it, then spend lots of money to bury it in the ground and protect it. It is not being used for new or more goods or services that increase it values in a manner that netflix is growing their new product or service. I want exponential growth! My guess is that some of the gold issues will set up for good short sales in the coming months.
