A better comparison
Would be like a drug user demanding cheaper smack from their dealer.
We are addicted to cheap crude. Much of our society is built on having a ready supply of petroleum - from our housing developments to out of town shopping to pizza delivery. And there is a fundamental limit on how much oil can be hauled out of the ground.
Blaming OPEC is stupid. There are well-understood limits on how much oil can be pumped out of a field and how fast it can be produced. A good petroleum geologist can give you those numbers, and almost any geologist will tell you that the OPEC countries are lifting as much crude as they can without doing irreparable damage to their fields. In fact, some of the World's largest producers have probably already done damage to their fields - largely by depleting gas pressure - by trying to exceed these limits in earlier years.
With the dubious exception of Saudi Arabia, there is no more spare capacity left in the World. Even if the OPEC countries were to start drilling tomorrow, adding secondary and tertiary recovery to their existing fields and improving their infrastructure, it would take 5 to 10 years to get that additional oil to market, by which time there would be even more demand. And outside of OPEC, things are pretty bleak, all of the largest non-OPEC countries are facing declining production figures and the rate at which new reserves are coming on stream is slower than the slowdown in existing production.
And no amount of rhetoric from Brown, Bush and the rest of them can stop peak oil. It might be here, it might be 10 years down the road, but it's almost certainly within spitting distance.
Mind you, the next time you're bitching about the price of petrol, remember that an irreplaceable geological curiosity pumped from kilometres under the one of the coldest, stormiest, most hostile seas in the World, piped through hundreds of kilometres of steel, transformed through a miracle of organic chemisty into a useful product, is only slightly more expensive than milk.
