My first experience with WalMart was when I needed fake fur for the stuffed plague rats I sell. I called the store to ask what color fur they had. The lady said, "various colors". The various colors included pale blue, bright fuschia, screaming turquoise, and horrendous orange. Not good rat colors. I found this out after a 90 minute bus ride, and a long climb up a steep hill. I was umimpressed.
The WalMart stores I have been in look dirty and messy. They offer a small selection. Half the merchandise is stacked out of my reach.

Now, selling plague rats has taught me the following, If a person has $5 they will not buy a rat. If a person has $50, they will buy a rat. If a person has $500, they will buy at least one rat, and perhaps 2 or 3. But a person with $5000 buys no more rats than the person with $500. The moral of this lesson is that the best thing for business is a large middle class. The NeoCons haven't figured this out yet. I very much doubt that they ever will.
