We have an issue with refining capability, the US hasn't built a refinery in 25 years, so it is an issue. I believe drilling our own oil, in our own country would bring the price down for us. It certainly won't help in the short term, but for long term it needs to be done. On the other hand, OPEC says there is no logical reason for oil to be this high, they are meeting demand, they have sources to meet demand and it's just panic making the price $70 a barrel.
I agree this is an issue, but it has absolutely nothing to do with our current price levels. Look, if we 'refining' was a definite issue, that means we would not be 'refining enough', which means we wouldn't have 'enough' refined gasoline in the market place, which means that we would not have 'enough' gas at the pump to meet our demand - and you would then start to see 'lines at the pump' because stations would not have 'enough' to pump into everyone's gas tank to meet demand.
There are no current 'refining capacity' shortages, because you can get all the gasoline you need at the pump. If there is a "shortage" tell me what part of the country there are 'lines' at the pump.
