It is supply and demand. Just because you don't understand economics doesn't mean it isn't true.
Demand is not the amount consumed. It is a curve of how much consumers are willing to buy at different prices.
"don't understand economics"?
Ha!
How about simple math?
If the price is up many times what the demand is that equals market manipulation, and price fixing.
On the other hand if "Demand is not the amount consumed", then the "curve of how much consumers are willing to buy at different prices" must be a measure of how badly you can swindle consumers before they lynch you.
