1. The price of oil is manipulated. As in most markets, the idea of a "free market" is a myth. I could claim that big oil and OPEC sleep in the same bed but that would be accusing them of incest.
2. The supply is limited, as is everything else, but oil is being discovered at a faster pace than we are using it. It will be kept in the ground. Many estimates say that there is as much oil under Iraqi sand as there is in Saudi Arabia.
3. Frankly I hope China and India don't go down the same path we took. For their sakes I hope they invest heavily in public transportation. I don't feel deprived when someone else does the driving. I kinda like it.
1. The price of oil is set an open market called the NYMEX. All grades of crude oil are set either higher or lower than the NYMEX price in relation to the energy content and "sweetness" (lack of contaminants) of the oil While some big hedge funds are long oil because they think the price is going up, other are short because they think the price is going down. The net result is only a slightly higher oil price.
2. Oil is not being discovered at a faster pace than we're using it. That hasn't been the case since the early 1980s. Oil discoveries are down substantially from their all time peak in the 1960s, that means oil production must eventually peak and start to decline, very soon
3. China is going exactly down the same path we took. Personal transportation is highly desired there, like it is here. So too in India. The Indian company Tata recently released the "Nano" for $2500. People in Asia are snapping them up.
It happens all the time. Increased demand against a static supply means higher and higher prices. The only way the bubble might burst is if people stop using oil. There's isn't a cheaper form of energy out there.
