It’s congress’s fault, not the companies. They’re a bunch of lying hypocrites. The increase has a lot to do with them systematically debasing our currency by drowning us in debt and bailing out wall street. No one talks about the dollar being the main reason for the price increases. Euro based economies aren’t complaining about oil increases the way we are.

Look at 2001. Oil was more euros than dollars. Now look at it.
