Only in theoretical sense. Supply and demand ops in the real world often exhibit surprising trends. We have demand in oil (and to a lesser extent in gas) that is climbing for a number of reasons and the motivations behind that demand can outweigh price...especially when prices are not anywhere near the worst they've been.
If anyone is immune from the law -- in more ways than one -- it's the oil companies.
Elaborate and bring evidence, or go home.
My reference was to your accusation that the Congress was trying to violate the Law of Supply and Demand. I thought I'd point out that gasoline seems to defy that law at will.
The vertical monopoly, the price-fixing and collusion, the artificially inflated prices -- all are examples of legal violations practiced daily by the oil companies. That in no way means that they are PROSECUTED as such. But the fact that they get away with it doesn't make it legal.
And whether it's legal or not, there is -- or should be -- some moral dimension to the marketplace too. Which is a laughable concept in the world of global mega-corporations.
