These legislatures are such a joke. This "speculation" or "bubble" can be directly attributed to policies that they vote for or can change.
Imagine if we weren't in iraq. Imagine if they have had the balls to be forward thinking and raise the mpg standards significantly. Imagine if they stopped giving subsidies and tax breaks to companies using old energy (oil, coal, nuclear) and instead either give none or give some to companies creating new energy alternatives. Just imagine if they didn't always have one hand on their wallets.
Instead of recognizing this and fixing our policies they just want to add another bandaid on top of existing trash. I tell you, the leaders of the greatest country on earth are a bunch of gutless wonders.
Speculators will always exist as long as we have a capitalistic society, they can otherwise be called investors.
