>If every corn producer sells at exactly the same price and there is no semblance of competition, then yes, I'd call them a cartel too - especially if their prices just happened to change all at the same time. Trying to pretend that prices at the pump just coincidentally rise by the same amount at the same time for all the companies is simply laughable. Cartels are illegal in the U.S. and Canada, and it is very disappointing that they are tolerated by our governments. I know that speculators are getting a lot of return on their investments, but that is not a good argument for allowing this sort of activity.

OK, you convinced me, I'll start buying government bonds. Investing in government does yield most.
