Jane Jacobs - The Death and Life of Great American Cities, p.243

A diversified mixture of uses at some place in the city becomes outstandingly popular and successful as a whole. Because of the location's success, which is invariably based on flourishing and magnetic diversity, ardent competition for space in this location develops...

The winners in the competition for space will represent only a narrow segment of the many uses that together created success. Whichever one or few uses have emerged as the most profitable in the locality will be repeated and repeated, crowding out and overwhelming less profitable forms of use...

Thus, from this process, one or few dominating uses will finally emerge triumphant. But the triumph is hollow. A most intricate and successful organism of economic mutual support and social mutual support has been destroyed by the process.

From this point on, the locality will gradually be deserted by people using for purposes other than those that emerged triumphant from the competition - because the other purposes are no longer there. Both visually and functionally, the place becomes more monotonous. All the economic disadvantages of people being spread insufficiently through time of day are likely to follow. The locality's suitability even for its predominant use will gradually decline, as the suitability of downtown Manhattan for managerial offices has declined because of this reason. In time, a place that was once so successful and once the object of such ardent competition, wanes and becomes marginal.
