"It's fairly simple, really," I said. "You can rebuild sections of the Denny Park area. Encourage people who will even up the demographic mix to move in. You'll have your own little population from which to draw focus groups. You can have your own stores where you can test product placement. You can employ some of the people and raise or lower their income to levels appropriate for whatever you want to test. You can create your own little world and it will pump out streams of data for you to analyze, all the while saving money."
