Banks, businesses, and governments colluded to steal trillions of dollars from second and third class citizens the world over in bail outs, debt deals, market schemes, and legalized financial scams. The did it publicly, without need for subtle pay offs or clever planning because they had already bought their way to legality. In the US it happens every election cycle. In other countries its the Golden Slide: They finish their terms as corporate back scratchers; these legislators, these politicians, and they never need worry again. Lobbying jobs, consulting positions, free lunches, country club perks, everything swings for them because they knew (as they started work) who had the money, who had their eternal financial security in hand.
The people see this massive wealth grab and at some level they think about the reasons they've abstained from the free for all. Firstly, its in an abstract money market, one they don't have an invite to. Seondly, they have morals, they know its not right to steal and cheat and lie. Thirdly, they would prefer to earn their way through life, they still feel guilt after all.
But it doesn't matter, people can take sums of money that beggar the imagination and not be arrested. They get a lifetime of knowing that the future is safe and secure. For everyone who isn't a member of the first class, you have to kick certain cans down the road; you have too many balanced in your hands already to pick them up. Once your caught up you can finally pick that responsibility up again, paying off the credit card or backpayments on the car, only to find that something else has to be dropped: you just don't have enough money.
The last generation did fine though! They managed to pay for all these things when they were more expensive. Why? Their jobs hadn't been shipped overseas, they hadn't had wages cut, they hadn't had medical and retirement security taken away. They hadn't seen all that money flow to Mr. Monopoly. And now we sit behind a counter making products we aren't proud of for people who won't remember consuming them ten minutes on. We lost everything and dammit, we're going to take it back.
That frustration sits there, simmering, waiting for the shooting of an unarmed man or bad hockey game to explode. And then the people imitate the habits of the rich and famous, the bigger people put on the pedestal as the pinnacle of modern life: we start to pillage. If we can't get it the right way, the legal way, the moral way, just grab it and run. Just burn down what you can't get. Get yourself financial security with a brick, a bat, and a burning tire.
