Imagine that a new technology comes along that spawns a whole new industry. Not only is this industry a revolution in how people lead their lives, it’s immensely popular and generates a big pile of cash. The field starts out wide-open with many small entrepreneurs, but gradually they become rich as they are bought out by a few big players. Soon, the industry has consolidated and re-investment slows dramatically. Those who made big money start to put it into real estate, specifically in Midtown Manhattan, Florida, and Los Angeles.
