So here is something I never thought I would write: a column about Sarah Palin’s ideas.

There was plenty of the usual Palin schtick — words that make clear that she is not speaking to everyone but to a particular strain of American: “The working men and women of this country, you got up off your couch, you came down from the deer stand, you came out of the duck blind, you got off the John Deere, and we took to the streets, and we took to the town halls, and we ended up at the ballot box.”

But when her throat was cleared at last, Ms. Palin had something considerably more substantive to say.

She made three interlocking points. First, that the United States is now governed by a “permanent political class,” drawn from both parties, that is increasingly cut off from the concerns of regular people. Second, that these Republicans and Democrats have allied with big business to mutual advantage to create what she called “corporate crony capitalism.” Third, that the real political divide in the United States may no longer be between friends and foes of Big Government, but between friends and foes of vast, remote, unaccountable institutions (both public and private).

In supporting her first point, about the permanent political class, she attacked both parties’ tendency to talk of spending cuts while spending more and more; to stoke public anxiety about a credit downgrade, but take a vacation anyway; to arrive in Washington of modest means and then somehow ride the gravy train to fabulous wealth. She observed that 7 of the 10 wealthiest counties in the United States happen to be suburbs of the nation’s capital.

Her second point, about money in politics, helped to explain the first. The permanent class stays in power because it positions itself between two deep troughs: the money spent by the government and the money spent by big companies to secure decisions from government that help them make more money.
