From this piece in The Economist:
His contempt for government resonates with people all over the world. ... In the euro zone they march against austerity ...
DOES. NOT. COMPUTE.
The theme of the article is, roughly, this:
They tend to be ordinary, middle-class people, not lobbies with lists of demands. Their mix of revelry and rage condemns the corruption, inefficiency and arrogance of the folk in charge.
And yet: they're marching against so-called austerity, which is just a slight decrease in the rate of expansion of the corruption, inefficiency, and arrogance?
Some of the other examples sound remarkably like "We demand our subsidies!" Also known as: "Where's our share of the corruption?"
Makes one suspect that the protesters in question are highly confused... or that the author is.
But... this business of middle-class people getting out and protesting in the streets. Could It Happen Here?
Durn tootin' it could, and it will.
See, middle-class folks don't generally do that sort of thing for various reasons, the most famous being that We Have Jobs.
Only, increasingly, We Don't. When you have a large chunk of the former middle class becoming chronically unemployed (and discovering that the so-called "safety net" is reserved for the welfare caste, and not available to down-on-their-luck taxpayers), the restraints will be falling off.
Ergo: yes, we will be seeing that sort of thing here. The Tea Party is just a well-mannered preview*. Throw in the ongoing slow-motion economic disaster and the State's increasingly open penchant for treating the People as the enemy, and... well, expect ugliness.
* The Infest Whatever movement was an ill-mannered bit of fakery staged by the younger sons of the Aristocracy, and doesn't count.
