A small pioneering innovative business starts in a dull neighborhood. Before long it is thriving and attracting significant foot traffic. Other businesses quickly rush to the neighborhood. I have seen such magnet businesses in the clothing field, as restaurants and as interesting repair shops.
Invariably as the neighborhood expands and thrives, the original business that created the locus of success, the magnet business, finds its rent rise and become excruciating. The original magnet business is forced to leave.
I have never found a solution to this problem. How does a neighborhood protect the founding magnet business?
This is a problem that needs to be solved and there is no simple solution. When the magnet store disappears the neighborhood enters a downward slow death spiral. The coherence is gone.
