Shane asks an important question that is too often brushed aside. To answer this I'd like to flip the situation to one where high prices are desired and relate what happened at a homeowner's association meeting I attended a few days ago in my neighborhood.
One of the members of the association is the primary developer of the properties here, and is still developing the few remaining lots and lives either in our neighborhood or close by. A lady at the meeting was upset with him for selling houses below the price she purchased hers for about 2 years ago and implied that he was dragging down the values of the houses in our neighborhood (I think she's trying to sell right now and is unable to get what she paid for it). He was very diplomatic and took quite a bit of unjustified criticism while gently trying to point out that it really is in his best interest to sell as high as he can, but no one's willing to pay more money right now so it's not like he can force them to. They are both genuinely nice people, but my take on the situation was that she lacks an understanding of basic economic realities and was blaming him for something he simply cannot control. Can we reasonably expect him to refuse to sell his houses in an attempt to artificially prop up prices, all the while paying interest on the mortgages he took out to build them and tying up his equity so he can't build more houses and make a living? Too many people bought too many houses the last 3-4 years, and now there are far fewer people to buy a similar number of houses. Housing prices cannot do anything but fall in this situation, since buyers have all the leverage--they can just go find another house (or ten) if a seller doesn't like the price they offer.
It's no different with oil, and right now those who buy oil futures are concerned that energy demand will decrease due to lower economic activity. In fact, this is already happening, just search for "falling oil demand" on Google. Excessive oil prices will inevitably lead to belt-tightening by and bankrupting of businesses that waste oil which in turn will inevitably lead to lower oil use and lower prices. It's all about supply and demand--there's no great conspiracy orchestrating the price of oil, though many politicians on both sides would like us to think so when it's to their advantage.
It's also important to keep in mind that the energy prices we saw in the late 1990s were unsustainably low and led to an explosion of wasteful business and individual practices. This in turn led to an explosion in worldwide demand for oil, which drastically increased the price as more people wanted a finite resource. As a consequence, this year we've seen unsustainably high oil prices which are in turn forcing both business and individuals to modify their behavior and use less oil.
In short, today's high oil prices simply indicate that we're in an uncomfortable period of the constant feedback loop that makes market economies so effective (though painful at times), and now we're having to adjust our behavior to account for the reality that has been there all along; namely, that oil is not a limitless resource. Given that fact, I doubt you'll find too many dissenters to the view that finding a new source of energy should be our country's number priority since something like 80-90% of the world's oil reserves are controlled by unfriendly dictatorships (as large as Exxon-Mobil is, they're a bit player on the world market). At present they want our money and are not making as much trouble as they could, but unfortunately history teaches us that a severe threat is often the only way to force humankind to make a change as significant as the one we're facing now with regards to energy, so it's taken us a long time to get to this point. That is, assuming we have even gotten there yet.
