JAMES PETHOKOUKIS: Why is Romney doing such a lousy job defending his record at Bain Capital? “Not only is Romney’s Bain record on trial here, so is the whole idea of Schumpeterian, entrepreneurial capitalism where ‘creative destruction’ creates a massive net benefit for society. This is exactly the idea that the Obama reelection campaign is attacking as promoting unacceptable levels of inequality. (Apparently bad government investments — like in Solyndra — that lose jobs are OK.)”
