During this interview Spencer H. MacCallum elaborates on his concept of entrepreneurial communities as a provision of common services through ordinary relations in the market place. He explains how developed neighborhoods attract entrepreneurial interest, since they provide an opportunity to offer or improve community services, at the same time that a profit can be made. It is his belief that land value increases as both the occupants and entrepreneurs gather in commercial relations raising the concern for a continuous success, which eventually leads to a common benefit for the parties involved. MacCallum provides, as well, historic and modern examples of this type of communities and its evolution, in order to illustrate his idea.
