Should have bought silver. You know, for the werewolves that are inevitably going to appear under cover of the societal collapse . . .
what if I want protection from werepossums? Should I buy unobtainium?
None of the hyperinflationists' stories check out. We'll have to create tons of currency out of nowhere to pull that off. Which the Fed has done, but that doesn't matter, because it's been controlled, and because interest on debt can absorb the excess cash.
No need for unobtanium; a sharp blow to the snout and werepossums sull up and play dead.
Gas prices are probably going up for three reasons. First, demand is increasing as most countries emerge from the recession. Second, the dollar is falling as we electronically print more. Third, people have grown to expect it will continue to go up, so they try to keep full tanks to beat the expected future hikes. This causes prices to rise as more gas is sold and therefore raising prices is less risky; your gas may sell a bit more slowly than your neighbor's, but it will still sell, and likely as quickly at the new higher price as it used to sell at the lower price. But this phenomenon is self-extinguishing; it raises demand short term, but pretty soon everyone has a full tank and gets tired of buying gas every day or two, and then prices stabilize or even fall as retailers drop prices to increase volume.
As far as riots, liberals have been talking for decades about artificially raising gas prices to $7 or even $10 per gallon to cut demand. I see no reason that $4 gasoline, or $5 or $6 gasoline, would cause any widespread riots. Much more likely that it would simply cause more people to drive less and more people to take mass transit, just as did $5 gas after Katrina. Americans are NOT like Europeans, rioting every time something happens that we don't like. Even most Europeans don't do that. And the food riots (such as in Mexico) are much, much different. There's a huge difference between not being able to afford enough food to avoid starving, and not being able to afford gas to go hang out in the mall or visit your gym. America is still a country where poverty wears hundred dollar running shoes.
