Again, people will rise up when they are right for the time. It's not now. Things aren't bad enough yet. Lifestyles haven't dramatically changed yet. When that comes, you will know. When credit cards stop working, when people don't have jobs, and when prices go out of control, we'll see some fireworks. Until then, everything is going to tie over for the short term.
I wouldn't worry about whether or not we have it "in us". We do. We all do. There's no particular race, religion, sex, national origin, or age where we determine our fates. Revolutions have occurred in Africa, North America, South America, Oceania, Asia, and Europe. If people with nothing but a towel to cover their asses can rebel, I suppose Americans can too. It's been going on for a long, long time and no matter what year it is, whether it be 1008, 2008, or 3008, the same rules apply.
Nature has a tendency to clean out the bad stuff. Markets do it, nations do it, wildfires do it, etc. etc. Bad stuff doesn't flourish in this world forever. In the end, the underbrush of corrupt politicians and big government will burn itself out.
Remember Ron Paul saying having a strong currency and a Central Bank is impossible?? His reasoning was the temptation was too great to give humans the power of a printing press. People in the Government that have integrity will do what's necessary. The American People can do the rest.
