Haven't followed american politics lately, but I'm pretty sure $10/gallon gas would start a violent revolution in the US.
Violence, yes. A revolution, no. Americans have become a kept populace, in general, over the course of my lifetime. Middle class America has become materialistic and soft. So much so that the only thing that I can imagine getting them off of the couch would be the threat of loss; loss of their comforts, loss of their jobs, loss of their pensions. And even if that happens, far too many have been asleep for far to long to understand what would be happening, and would join the riots without a cause. If that day comes, I'll be hanging out with my family at my Mom's farm. The meek shall inherit the Earth.
Woe to anyone who sneaks upon the farm looking for a free meal without permission, however.
