LONDON burns. The Arab Spring triggers popular rebellions against autocrats across the Arab world. The Israeli Summer brings 250,000 Israelis into the streets, protesting the lack of affordable housing and the way their country is now dominated by an oligopoly of crony capitalists. From Athens to Barcelona, European town squares are being taken over by young people railing against unemployment and the injustice of yawning income gaps, while the angry Tea Party emerges from nowhere and sets American politics on its head.

What’s going on here?

There are multiple and different reasons for these explosions, but to the extent they might have a common denominator I think it can be found in one of the slogans of Israel’s middle-class uprising: “We are fighting for an accessible future.” Across the world, a lot of middle- and lower-middle-class people now feel that the “future” is out of their grasp, and they are letting their leaders know it.

Why now? It starts with the fact that globalization and the information technology revolution have gone to a whole new level. Thanks to cloud computing, robotics, 3G wireless connectivity, Skype, Facebook, Google, LinkedIn, Twitter, the iPad, and cheap Internet-enabled smartphones, the world has gone from connected to hyper-connected.
