Did you read the article? It was a scam.
Do you mean by Scam that profits were excessive?
Does buyer beware still apply?
When Apple charges $400 for an iPad which costs them $25 to manufacture in China, does that qualify as a scam?
Why I can buy airline ticket to go from LA to NY cheaper than going from NY to Minneapolis? Tail winds?
Are excessive profits now the new taboo?
I do not need to read any article which claims profits were excessive and therefore it is a scam. Oil is now selling for $57 per barrel and there are no shortages. A few months ago it was $110 per barrel. Was that then a scam by oil companies for artificially rigging the price higher? Scams every where! Or may be it is just the dirty free market capitalism at work.
