Consider first how Republican politicians have portrayed the modest-sized if growing demonstrations, which have involved some confrontations with the police — confrontations that seem to have involved a lot of police overreaction — but nothing one could call a riot. And there has in fact been nothing so far to match the behavior of Tea Party crowds in the summer of 2009.

Nonetheless, Eric Cantor, the House majority leader, has denounced “mobs” and “the pitting of Americans against Americans.” The G.O.P. presidential candidates have weighed in, with Mitt Romney accusing the protesters of waging “class warfare,” while Herman Cain calls them “anti-American.” My favorite, however, is Senator Rand Paul, who for some reason worries that the protesters will start seizing iPads, because they believe rich people don’t deserve to have them.

Michael Bloomberg, New York’s mayor and a financial-industry titan in his own right, was a bit more moderate, but still accused the protesters of trying to “take the jobs away from people working in this city,” a statement that bears no resemblance to the movement’s actual goals.

And if you were listening to talking heads on CNBC, you learned that the protesters “let their freak flags fly,” and are “aligned with Lenin.”

The way to understand all of this is to realize that it’s part of a broader syndrome, in which wealthy Americans who benefit hugely from a system rigged in their favor react with hysteria to anyone who points out just how rigged the system is.
