Not sure I would call Walmart "the devil" but it is disingenuous to lump these retailers together as "all the same." Both in their corporate operations/philosophies AND how they relate to the destruction of smaller market radio. "Both sides are equally bad" arguments let the actual bad player off the hook. Which is why folks who are not arguing in good faith (or have a weak argument) tend to use it A LOT to try to make their point.
As it affects radio, they're all the same. When it comes to small local businesses, they're all equally bad, if only because of the volume of goods they sell along with their ability to undercut in pricing, and the fact that they're national chains, operating out of some corporate office in a big metro somewhere, maybe 2000 miles away.
The box stores -- all of them -- were so effective against smaller and local business because they were like a mall within a store with centralized, cost-cutting national distribution operations. This applies to every box retailer. One stop shopping for everything, at pricing that the little guy couldn't compete against because the little guys couldn't order goods by the container-load.
Walmart killed businesses in small towns across the rural USA only because the other two other dominant box store giants generally never bothered to locate where rural and poor people live. KMart located stores in smaller places, but they even seemed to avoid the little towns where Walmart located. As you admitted, the other big box stores mostly stick to the burbs. They go where the money is.
Walmart had a worse effect on small town, local businesses, which obviously affected small town, local radio. I think that fact is
undisputed. KellyA even talked about this sort of thing from his direct experience. Bossbill, too.
Look, if people hate Walmart for some of their other practices, too, fine. Go ahead. I'm no Walmart fanboy. But I'm talking about how
all of this is affecting the little guy, and how it is affecting radio. I just saw a local grocery store go under. Another one went under during the Great Recession and the building's been empty ever since. Everyone is going to Costco, Walmart, Target, Kroger instead. Take your pick. And
none of those national, centralized operations are advertising on the local, suburban radio station.
