It has come to this: The crux of the political left's complaint about Americans is that they are insufficiently materialistic.

For a century, the left has largely failed to enact its agenda for redistributing wealth. What the left has achieved is a rich literature of disappointment, explaining the mystery, as the left sees it, of why most Americans are impervious to the left's appeal.

An interesting addition to this canon is "What's the Matter With Kansas? How Conservatives Won the Heart of America." Its author, Thomas Frank, argues that his native Kansas -- like the nation, only more so -- votes self-destructively, meaning conservatively, because social issues such as abortion distract it from economic self-interest, as the left understands that.

Frank is a formidable controversialist -- imagine Michael Moore with a trained brain and an intellectual conscience. Frank has a coherent theory of contemporary politics and expresses it with a verve born of indignation. His carelessness about facts is mild by contemporary standards, or lack thereof, concerning the ethics of controversy.

He says "the pre-eminent question of our times" is why people misunderstand "their fundamental interests." But Frank ignores this question: Why does the left disparage what everyday people consider their fundamental interests?

He says the left has been battered by "the Great Backlash" of people of modest means against their obvious benefactor and wise definer of their interests, the Democratic Party. The cultural backlash has been, he believes, craftily manufactured by rich people with the only motives the left understands -- money motives. The aim of the rich is to manipulate people of modest means, making them angry about abortion and other social issues so that they will vote for Republicans who will cut taxes on the rich.

Such fevered thinking is a staple of what historian Richard Hofstadter called "the paranoid style in American politics," a style practiced, even pioneered, a century ago by prairie populists. You will hear its echo in John Edwards's lament about the "two Americas" -- the few rich victimizing the powerless many.

Frank frequently lapses into the cartoon politics of today's enraged left, as when he says Kansas is a place of "implacable bitterness" and America resembles "a panorama of madness and delusion worthy of Hieronymus Bosch." Yet he wonders why a majority of Kansans and Americans are put off by people like him who depict their society like that.

He says, delusionally, that conservatives have "smashed the welfare state." Actually, it was waxing even before George W. Bush's prescription drug entitlement. He says, falsely, that the inheritance tax has been "abolished." He includes the required -- by the left's current catechism -- blame of Wal-Mart for destroying the sweetness of Main Street shopping. "Capitalism" is his succinct, if uninformative, explanation of a worldwide phenomenon of the past century -- the declining portion of people in agricultural employment -- which he seems to regret.
