Either is a valid marketing approach. It just depends on what your product is. For ex., it would be foolish to try to sell Ferraris in the inner city. A coke dealer or two might buy one, but (crime aside) you wouldn't make it. On the other hand, it probably wouldn't be good to put a "Dollar Store" on Rodeo Drive, although, oddly, we have a "Goodwill" store in Centerville, OH, one of the richer suburbs of Dayton, and my wife knows MANY fairly well-to-do people who shop there. I'm sure Clark Howard would!
I've known a few myself but I suspect Goodwill would locate a store in the area as much for a dropoff point as anything else, no? I dunno.
You missed my caveat in my post following re who prgramming, hence, advertising might be directed towards. Can you see how conservatives(middle class(?)) and flyover country may have been relegated to second class status by the media? I mean, WHO actually watches this stuff?
