Our take: Romney has a net worth of $250 million, but Bloomberg suggets he's a "pauper" among buyout firms, and if he had stayed at Bain Capital LLC, he'd be worth much more.

"While private-equity peers Stephen Schwarzman, Henry Kravis and David Bonderman have each accrued a 10-figure net worth, the Republican presidential nominee missed out on his industry's most lucrative era, a decade when he managed the Winter Olympics, served as governor of Massachusetts and ran for president. Had he stayed at Bain Capital LLC, he'd be worth more than $1 billion, according to the Bloomberg Billionaires Index.

"The Republican candidate, while still reaping some profits from Bain as an investor, was far from the center of the action and negotiated his exit from Bain before private-equity firms started going public.

"Buyout firms like Bain from 2000-2010 saw their funds, deals and paychecks reach record-setting sizes as they snapped up name-brand companies such as Toys "R" Us Inc. and Dunkin' Brands Group Inc. Schwarzman's Blackstone Group LP (BX) led an effort to take the firms public, locking in personal gains for founders. In 2007, KKR's Kravis labeled the era a "golden age" for the industry."
