Mitt Romney was not a businessman; he was a master financial speculator who bought, sold, flipped, and stripped businesses. He did not build enterprises the old-fashioned way—out of inspiration, perspiration, and a long slog in the free market fostering a new product, service, or process of production. Instead, he spent his 15 years raising debt in prodigious amounts on Wall Street so that Bain could purchase the pots and pans and castoffs of corporate America, leverage them to the hilt, gussy them up as reborn “roll-ups,” and then deliver them back to Wall Street for resale—the faster the better.

The larger point is that Romney’s personal experience in the nation’s financial casinos is no mark against his character or competence. I’ve made money and lost it and know what it is like to be judged. But that experience doesn’t translate into answers on the great public issues before the nation, either. The Romney campaign’s feckless narrative that private equity generates real economic efficiency and societal wealth is dead wrong.
