The demand for gas and oil is general is down; there's less people driving because of the extremely high gas prices we had last year AND a lot more people are unemployed so they don't need to be driving since they aren't going to work.
Furthermore, the supply is up. The price for a barrel of oil is lower compared to last year (around $30~$40 per barrel) and OPEC is considering lowering the amount of barrels they put out since the supply is so high and demand is lower than previous years.
And yet the price for a gallon of gas has been increasing. In California, the price has gone up by at least 30 cents just this month. How can this be?
How can the law of supply of demand be failing like this? Could it be possible that oil companies are intentionally manipulating supply by purposefully choosing to refine less oil and price gouging consumers? Isn't this kind of profiteering illegal?
Are a lot of books going to need to be rewritten if the cornerstone of economy, the law of supply and demand is no longer valid?
Please explain.
