It's going up because Obama didn't change the regulations that Bush shoulda changed in regards to commodity trading that would tend to keep the pure speculators out as intended in long stadning trading rules that Clinton changed in 2000. That's a pretty long discussion - but speculators can only move market prices where the other market parties are let them (i.e. those more integral parties have to be complicit in the movements), and their artificial effect on the market can only avoid reconciliation with the reality of the fundamental market conditions for so long (although, it is true that much damage can be done in the mean time).
Obama now risks the same stupid thing that Bush allowed; a devastating, specific hit to every single American and every last piece of the economy. Well, I think it is extremely unlikely that we will see something close to the peaks we saw last summer - we have a new ally in preventing that from happening now - OPEC. They learned their lesson this last time around, and they now realize that they have to be as vigilant in fighting the prices getting too high, as they are in fighting the prices getting too low. Yes, they raked in a bunch of cash very quickly, but they now understand that that hurt their long term ability to make money. Again, a long discussion - but most of the parties involved will now be fighting on the same side the next time that oil prices try to spike.
Oil should be at $30 or less. Right now Obama is allowing, at $50, some $500 million per day, $15 billion a month and nearly $200 billion a year to start leaving the national economy. This may be the straw that breaks Obama's back. I agree that this economy cannot afford to have oil be much more expensive - the huge relative savings realized from relatively low energy prices is one of the few things working in favor of the our economy right now. But, your numbers may need a little tweaking, because a good bit of that excess oil cost does stay in the national economy. Our net imports of petroleum products total about 10-11 million barrels/day. The point is still the same, and valid, though.
