Without Venezuela we would be paying much, much more.
You are completely mistaken. Venezuela, along with Iran, are the only two OPEC states that are producing BELOW their quotas. Chavez has trashed the state oil company so badly, treating it like his cash cow, to finance his soup kitchens and other welfare programs, that it's on its knees and cannot produce. If you read the news about Chavez's trip to Iran and Russia, he is openly demanding HIGHER oil prices. The Saudis are telling him no, but this is what he wants.
