>In other words, if Bain, KKR, and Vornado had never come along, Toys 'R' Us wouldn't be doing stellar, but it probably could've muddled through. Maybe. It was already on a downward spiral. There's pretty much zero evidence that, left as a public company, they'd have figured out a way to reboot. It's not like there aren't plenty of other retail chains in dire straits.
Bain and KKR's turn-round strategy was largely a joke: They basically floated a bunch of trial balloons to the press, arguing that they weren't going to just be a toy store anymore (basically become a walmart or target) but that was scuttled. After that, they just decided to control costs as tightly as possible. Very little innovation.
Prior to the buyout, there was a team inside Toys 'R' Us that was trying to clone Amazon's e-commerce success. It died with the buyout. Bain and KKR thought they had a better plan: they didn't.
