The Wall Street Journal has examined 77 businesses in which Bain Capital invested during 1984-1999, the period in which Mitt Romney headed the firm. Its findings show that 22% of the firms filed for bankruptcy by the eighth year after Bain first made its investment, some with large job losses. Additional 8% of the firms were in such bad shape that Bain lost all of its invested capital. Only a small number of firms produced most of the returns- 70% of the gains come from 10 firms. Of these 10 firms, four were later found in bankruptcy court. Another aspect mostly overlooked is that where large job gains were made they were mostly in lower wage retail jobs at Domino's Pizza, Staples and Sport's Authority, and did not involve the kind of innovation that produces sustained advantages.
