In Warren Buffett's case, I'd say there certainly is value in scouting out profitable, well-managed companies and giving them access to a large centralized pool of capital. Probably not $100 billion worth of value, but I do think the Berkshire Hathaway umbrella helps the acquired companies to grow beyond what they'd be able to achieve without it.
