To Save a Neighborhood, Ban a Dollar Store?
&quot;It’s hard to tell whether the increased dollar stores have harmed health, researchers say&quot;<p>The cities are so worried but there is no evidence health is impacted.<p>Maybe they should look at the reasons why supermarkets don&#x27;t want to open, but convenience stores do.<p>It may simply be that it is unprofitable. Supermarkets run on razor thin margins and require significant volume.<p>No amount of zoning will change that.<p>Edit: Maybe providing discounted&#x2F;free public transport to new or existing supermarkets would change things.
