Its not very nice but its very true. Ever since commodity traders were allowed to sell goods on paper rather than actually possess them first the price of everything goes up as they game the system.
The futures market provides some very useful functions such as price discovery and hedging for the physical market so the companies lock in and/or protect against sudden price swings right before delivery of the physical commodity.
Sure, the traders play their games, but modern life in the real economy would be far more difficult without them.
