Josh Barro has an interesting...

...and balanced piece in Forbes, of all places, about --you guessed it! -- Mitt Romney and Bain Capital (my emphasis):

The question [Romney] should be asked, then, is what policy implications arise from the economic shifts of the last few decades, driven (in small part) by private equity. Does rising income inequality mean that fiscal policy should be more redistributive? Does a reduction in job security call for a stronger safety net? Do new workforce needs mean we need a shift in education and training policies?

It’s worth noting that, as Governor of Massachusetts, Romney’s signature policy achievement was a universal health care program—that is, a safety net program that reduces the cost of job loss or income loss.
