Half as many people will not support half as many enterprises In a given geographical territory, half as many people will not support half as many such enterprises spaced at twice the distance.

Tossing an idea around Can we do anything to increase creativity? There are training courses, and books, as well as “brainstorming sessions” which are supposed to do this.
