No the key word is YEARS. I am familiar with firms such as Bain. The services they provide last only a few months to a couple of years. Most of the examples you cited had a time frame of close to a decade of company operation after Bain left. Plenty of time for a multitude of things to happen that may cause a bankruptcy outside of Bain's influence. I know that doesn't fit your argument but the reality is that there is too much time that has gone by for these companies to blame their bankruptcies on Bain.
" I know that doesn't fit your argument----- but"
The day after the Washington Post story, the New York Times detailed instances when Romney and other Bain executives earned large sums at a time when some companies they were involved with failed.
A key paragraph:
The private equity firm, co-founded and run by Mitt Romney, held a majority stake in more than 40 United States-based companies from its inception in 1984 to early 1999, when Mr. Romney left Bain to lead the Salt Lake City Olympics. Of those companies, at least seven eventually filed for bankruptcy while Bain remained involved, or shortly afterward, according to a review by The New York Times. In some instances, hundreds of employees lost their jobs. In most of those cases, however, records and interviews suggest that Bain and its executives still found a way to make money.
The New York Times published this response from Bain Capital:
We understand that in a political campaign some may distort or our investment activity by cherry picking a few negative situations while ignoring our overall track record. But, the truth is that less than 5 percent of our companies filed for bankruptcy while under our control". UNQUOTE

AND THE TASTE OF CROW, I MIGHT ADD.
