To counter your point Brian, I doubt we would have the same type of rage here in the US. What it comes down to is, we are too damn lazy and dumb. XD
Bear with me. We, as a country, cannot even make up our minds on leadership for two years. Now, for the sake of not making this political, I will not name parties or leaders or topics.
In 2008 we elected a president. This is a president that was very open about what he planned on doing in office but for some odd reason people still denied a lot of it, calling others fear mongers.
He was a huge change since the previous administration but after about a year, it seemed that the country could no longer stand to see him or members of his party in office. Which is ridiculous because they should've known what they were getting into; he was open about his views.
Then in 2010 a historic change took place and took so many members of his party out of office. TWO YEARS. We can't keep on party in office for more than TWO YEARS?! Why is this? People must have been uninformed or apathetic.
Europe on the other hand moves, almost indefinitely, in a certain pattern; they move toward socialism. I am not saying socialism is good or bad, for I can't around these parts, but the effect is has had on a lot of these countries has been significant.
People are enraged at the POSSIBILITY of the cost of their entitlements going up, i.e. universities. They riot in the streets. They become violent.
Is it just me, or can I not think of one similar instance of this here in the US? It is because we as a country cannot agree on one thing. This is not a bad thing. It will just take us longer to get where Greece, France, the UK, and so many others are today.
Of course as the condition of society degrade the population will become more prone to violence and rage but for now it is not something to worry about.
