And this helps how?

I saw in the paper this morning where both Hillary and Barack have proposed increasing taxes on oil companies to alleviate the high gas prices. Maybe I just think too logically, but I can't figure out how that will help. Everybody knows that when a business has to pay higher taxes, they pass the cost on to the consumer. We'll see it from the oil companies in higher prices at the pump. Can some of you explain to me the rationale behind this plan?
