Still, Walton told Corporate Dealmaker's Suzanne Stevens at the recent CD Forum in New York, that an us-against-them mentality is why we don't see more strategics teaming up with PE firms. And it's too bad, he says, because in the current volatile environment, such partnerships make more sense than ever.
