Trying to get a set of policies through Congress isn't a "revolution." Rejecting fossil fuels is something the masses support in theory, but not enough to end up with gas shortages and higher fuel prices. What America actually does have is a poverty crisis, and the longer we ignore (or even deny) it, the more it sinks the country. People want a representative govt. Today, the rich have full representation, the middle class have some, and the poor have no representation whatsoever. That's a pretty shabby excuse of a democracy.
As a candidate, Obama repeatedly pointed out that if we wanted change, we would have to organize, get to our feet and demand it from Congress. We almost did that, too, with Occupy, but before we could even catch our breath, Dem pols and liberal media redefined Occupy as a "movement of middle class workers." The rest of us -- the poor, and those who get why unrelieved poverty is sinking the US -- finally walked away. Those who aren't on the right are deeply divided today, and it would have been wise to begin addressing this years ago.
A "revolution" would have required daring to address the reality that not everyone can work (health, etc.) and that there aren't jobs at all, using our own history as proof of why poverty relief is essential to any chance of rebuilding the middle class. A revolution takes courage, and courage -- even enough courage to point out that the emperor (our corporate state) is naked as a jaybird -- is in short supply.
