The Business of Business is what makes the world go round. So it is, so it always was. I think a lot of people make the mistake of thinking this is all something new, but as a bit of a history nut (reader), I can assure you that it is as old as time. I just finished a book about the history of RI, for instance, and the entire ebb and flow has 100% to do with MONEY (business). Money from the slave trade, from the rum trade and from other ventures. Back then, the government didn't even attempt to fool people as far as it's business interests. The bigwigs in power flat-out stated their purpose as being "for the business man", which in general worked out to be against the working people (most people).

According to economic theory, energy companies can charge whatever they want at any time. The exception being regulated utilities. I agree that more regulation is needed, but the only party to do that is the big bad government that everyone is so quick to blame for everything.

Back to the subject at hand, I also believe in regulation of the energy markets....and definitely making it tougher for a little bit of money to control a lot of oil. Nothing wrong with speculation, but it has to be kept within the bounds of knowing that the players can make good on bad AND good bets. They obviously could not do that with the current crisis....that is, make good on their bets against the housing market, etc.
