It's always been about the profit; otherwise, what's the use? No one wants to admit it, but if YOU were sitting on all that oil, and you stood to make a handsome, even outlandish or obscene profit, would you sell it for less? It's about supply and demand plain and simple. Now, if you're doing illegal things to corner the market or engage in other unfair practices, then that's a different story.
Invent or discover some other fuel that contains the same amount of energy in as small a package, that is easy to transport and distribute and relatively safe to store at a similar price and you can give it away for free or at a really low price.
I am not defending the energy business, or am I attacking it. It's done a pretty good job of providing cheap oil. In fact, adjusted for inflation, gasoline is still a cheap bargain.
