If things continue in the direction they're heading, at the speed they're heading...
I mean, if you're not worried about this, and if you don't see how real a possibility it is, then you're really not paying attention. The riots happening in London right now don't just happen because some teenagers are bored or because the cops shot some guy. They can only really happen in a society that has been driven to desperation, that has lost all confidence in legitimate means of political discourse and turned to violent ones instead. And the economy is only going to get worse, and zero politicians, here or in Europe, are proposing actual solutions.
Obama gets up there and says that America will always be a triple A nation, and he looks like a total idiot. I'm sure he knows that he sounds like an idiot, the dude's intelligent and clearly has access to more information than most people. But he sounds like an idiot. The economy is in free-fall. There never was a recovery, which is why the "jobless recovery" meme was bull. The markets are now realizing this, and retreating like frightened animals into the one place they think is still safe.
Full-scale riots and mass protests probably won't occur until at least 2013 when a Republican is president and his/her economic policies just make things worse. By that point what remaining confidence in the political system there is will be lost.
I like how you say things no one else really wants to hear, and I think you're right here. I'd like to think Mitt Romney would instantly fix things, but I know that's not the case - it'll take years for America to recover. America should be pretty interesting around 2014...
