That's what everyone said about oil going over $80, then $100. It had no problem going up to $147 before the credit and real estate crisis.
Your premise, in theory, is valid. Problem is, it's only in theory. The reality is that no alternative fuels are readily available and won't be for 20+ years. It will be $300 by next summer, and $500 a barrell by summer 2011, and $10.00 gas will be "cheap".
Why so gloomy? You say this as if $300 or $500 / barrel oil is a bad thing?
...and supposed to make everyone unhappy. It doesn't. One man's hell is another man's paradise I suppose.
I personally wouldn't have a problem with $300 or $500 / barrel oil. Infact, it would make me quite happy.
Guess What? Overnight, while most people slept, ...gas went up 10.22 cents per gallon!
Isn't that great?!
