The left-wing site Salon published on Sunday a 3,000-word excerpt from an essay by Paul Krugman and Robin Wells (his wife) published in The Occupy Handbook, a collection of essays from a spray of left-wing economics writers (plus Tyler Cowen) released yesterday in support of the leftist sit-in. From the book description at Amazon: "A guide to the occupation, THE OCCUPY HANDBOOK is a talked-about source for understanding why 1% of the people in America take almost a quarter of the nation's income and the long-term effects of a protest movement that even the objects of its attack can find little fault with."
Under the full headline "Economy killers: Inequality and GOP ignorance -- By failing Econ 101, Republican leaders failed the country and repeated the errors that caused the Great Depression," Krugman and wife spent almost 3,000 words blaming conservatives for the "rising inequality" that has caused an ineffective response to the financial crisis of 2008. In other words, don't blame Obama, but "the right."
America emerged from the Great Depression and the Second World War with a much more equal distribution of income than it had in the 1920s; our society became middle-class in a way it hadn’t been before. This new, more equal society persisted for 30 years. But then we began pulling apart, with huge income gains for those with already high incomes. As the Congressional Budget Office has documented, the 1 percent -- the group implicitly singled out in the slogan “We are the 99 percent” -- saw its real income nearly quadruple between 1979 and 2007, dwarfing the very modest gains of ordinary Americans. Other evidence shows that within the 1 percent, the richest 0.1 percent and the richest 0.01 percent saw even larger gains.
By 2007, America was about as unequal as it had been on the eve of the Great Depression -- and sure enough, just after hitting this milestone, we plunged into the worst slump since the Depression. This probably wasn’t a coincidence, although economists are still working on trying to understand the linkages between inequality and vulnerability to economic crisis.

So how did we end up in this state? How did America become a nation that could not rise to the biggest economic challenge in three generations, a nation in which scorched-earth politics and politicized economics created policy paralysis?
We suggest it was the inequality that did it. Soaring inequality is at the root of our polarized politics, which made us unable to act together in the face of crisis. And because rising incomes at the top have also brought rising power to the wealthiest, our nation’s intellectual life has been warped, with too many economists co-opted into defending economic doctrines that were convenient for the wealthy despite being indefensible on logical and empirical grounds.
....
Why does higher inequality seem to produce greater political polarization? Crucially, the widening gap between the parties has reflected Republicans moving right, not Democrats moving left. This pops out of the Poole-Rosenthal-McCarty numbers, but it’s also obvious from the history of various policy proposals. The Obama health care plan, to take an obvious example, was originally a Republican plan, in fact a plan devised by the Heritage Foundation. Now the GOP denounces it as socialism.
The most likely explanation of the relationship between inequality and polarization is that the increased income and wealth of a small minority has, in effect, bought the allegiance of a major political party. Republicans are encouraged and empowered to take positions far to the right of where they were a generation ago, because the financial power of the beneficiaries of their positions both provides an electoral advantage in terms of campaign funding and provides a sort of safety net for individual politicians, who can count on being supported in various ways even if they lose an election.
....
In summary, then, the role of rising inequality in creating the economic crisis of 2008 is debatable; it probably did play an important role, if nothing else than by encouraging the financial deregulation that set the stage for crisis. What seems very clear to us, however, is that rising inequality played a central role in causing an ineffective response once crisis hit. Inequality bred a polarized political system, in which the right went all out to block any and all efforts by a modestly liberal president to do something about job creation. And rising inequality also gave rise to what we have called a Dark Age of macroeconomics, in which hard-won insights about how depressions happen and what to do about them were driven out of the national discourse, even in academic circles.
