This feels like the proverbial dollar left on the street that economists say should not exist, so I'm racking my brain trying to figure out what's stopping chains from replicating this. I wonder whether this alternate network is as scrupulous about source tracking and food safety regulations. Those costs could be driving up prices on the traditional retail side.
> what's stopping chains from replicating this Probably volume. Chinatown is extremely dense and has such high foot traffic that it makes sense to operate without refrigeration, with goods stocked from neighborhood warehouses. Most parts of the country don't have anywhere near that level of density, so the economies of scale wont work out like they do in Chinatown.
Most Americans buy groceries from a large corporate-owned store that they drive to and has everything, which compete with other large corporate-owned one-stop-shop that you have to drive to.
