gas and oil are funny things. While most things have a normal supply and demand curves, gas and oil have a "predicted" supply and demand curve. So gas and oil go up in a skittish almost schizophrenic way. And they lag on going down almost as if it takes time to relax.
for example, a hurricane is coming and we may have to shut down our refineries, prices shoot up. people hear about it and panic and prices shoot up again. the hurricane missed the refineries, and prices slowly creep down.
Same thing for the major holidays, people will consume more so we need to jack up the prices now while they are consuming because it will bump the price in the near future.
I don't think you could do this with any other commodity.
It also doesn't help if you keep doing record profits every quarter.
Some of the big issues are: Why do we have all of our refineries in the same spot and in the path of potential disaster all the time?
Why can't we drill where nobody lives? Why is there nearly a $1.00 a gallon in tax?
