Rockefeller was a case study in developing antitrust laws.

I guess it sort of has to happen this way, that the businessmen seizing opportunities to create market power are always going to be ahead of the regulators finding things that need to be stopped; because after all, the businessmen are paid more to do that job. I don't think it's conceivable that before Rockefeller began acquiring all of the refineries, that someone could have drawn up legislation to stop that, because it didn't occur to anybody. That's why Rockefeller was Rockefeller. And I don't think anybody could have drawn up legislation in 1980 to stop one company from dominating the operating system of personal computers. That wasn't an issue until we woke up and discovered that Gates had done it.
