I believe it is mostly a scam, that oil is artificially bid up. Mark my words, if oil soars again after the election, then it is proof that forces beyond our control are bidding up the price.
People are pissed off enough by losing their shirts in market and with home values in the gutter. Actually both market values and home values are more in line with reality, but in any case, if oil is being manipulated down, it is to keep us from really getting pissed off.
The biggest nightmare for those in charge, ie, horsethieves, politicians and CEO's, is that the American people should finally "get it", and understand what they are really about. They fear anarchy, which if things get much worse, they may actually experience first hand.
They keep us fighting among ourselves, confusing us, creating class warfare, when they are basically unaffected. But fortunately for them, we are stoned on Budweiser and idiot TV to realize what is really going on.
