Joe Klein:

But most of the anger we see and hear comes from people who are paid to be angry, on cue, on cable television--as opposed to people with actual grievacnes. Suddenly, the White House press corps goes barking mad over the AIG Bonuses. It is said that the bonuses are an aspect of the bust that the “public” can understand; in truth, the bonuses are an aspect of the bust that reporters can understand. Suddenly, the Obama Administration has a “crisis.” The President has to go on television and act as if he's angry, even though he knows these bonuses are the tiniest outcropping of outrageousness.

...

If you want to be angry about something, get pissed at a media culture that goes beserk about bonuses one week and forgets all about them the next. And be worried, quite worried, about a society for whom anger is a form of entertainment.
