All it took was $4 gas. All the Saudis have to do is drop their price to the point where gas is $2.50 again and suddenly all the US companies go under in 12 months. But think how much we'll save by having less than 10k troops in the middle-east someday.
Our increased production of oil is due to the new technology of fracking (fracturing the ground to get oil out of it). The situation is certainly not "We could have been fracking 15 years ago, but we didn't feel like it because Saudi gas was cheap". The energy sector is subject to the same process of technological advance that any other industry is. We came up with a new way to get oil out of the ground and figured o…
It's true that technology has improved, but it's likely that with more price pressure to improve the technology, these innovations would have come sooner. In addition, fracking is more work, period. It requires more energy than traditional drilling, and while this can be incrementally improved, it's fundamentally a much more energy intensive process that can't just be "optimized away."
