Conspiracy mongers ???
Perhaps you're speaking to some other Steve, but I never said there was a conspiracy ... and I don't believe for a second that an active conspiracy exists ...
Don't believe what I'm telling you if you prefer some other explanation ... your choosing to believe that traditional rules apply as if they were immutable principals of physics does make me a conspiracy theorist who doesn't understand economics or know the meaning of fungible ...
And if, by asking for specific examples, you mean you want names and dates ... well, it's not going to happen, is it? ... neither I nor anyone else can cite such examples or there'd have been bigtime action in the courts long since ...
But let me say this ... the 'broken pipeline' in Arizona that was blamed by the oil companies for the sharp rise in pump prices from Colorado to California (conveniently, just as a record number of holiday motorists were about to hit the road) just doesn't support the sudden 'cause' of high pump prices in IL OH, or NY ... in those places, I'm sure some other convenient 'emergency' is to blame ...
And yes, the basic laws of economics DOES also apply to big oil ... some of the rise and fall of prices IS legit ... but the fact is, a lot of that rise and fall is pure manipulation of the market ...
In driving from my home in the East Bay on Monday, I passed through no fewer than 6 'marketing zones' in the course of my 40 mile drive to San Jose ... each of those 6 zones has pricing from the oil companies that is different from each of the other 5 ... a gas station near my home, for example, actually has to pay a higher wholesale price to the oil company than the pump price INCLUDING TAXES at stations only 30-35 miles away ...
