While this may seem dire for U.S. consumers, it does not mean that OPEC holds all the cards. As a Saudi oil minister said in 1973: "The Stone Age didn't end because we ran out of stones." In other words, the Saudis understand supply and demand and the historical evolution of technology. If something was learned from the aftermath of the 1973 oil crisis, it is that high oil prices lead to technological solutions, reducing the dependence on oil at a global level (e.g., conservation, development of alternative energy sources, opening of new oil reserves). In some buildings, you can still see "turn off the lights when leaving" signs from those days.
