Evil doer corporatists, greedy speculators and reich wing
conservatrashers conspire to drive down the price of oil and gasoline:

The only possible motive is they are trying to reestablish the myth
that prices are set by an auction market based on supply and demand.

Isn't it interesting that all of the conspiracy theorists run rampant
when prices are going up but are strangely silent when prices go down?

It should be good for boating however (please note clever interjection
of an on topic subject).
