As a life-long Texan, this sounds ridiculous to me. A Wal Mart employee is more intimidating, simply because they're Texan?
This is not the 1850's.
(Oddly I’ve only seen unarmed, tired looking security in CVS. Perhaps they’re too cheap to pay for armed gaurds.)
It's not ever really geared at shoplifters though, as a lot of people seem to forget that shoplifting isn't really the biggest crime you can do in a store.
It wouldn't be the corporation arming the staff, it would be the staff arming themselves via a CCW/CHL. The first letter states 'concealed', so by definition you shouldn't see it.

Its less about any individual employee, and more about the general culture and nature of crime in the two areas. If I were a criminal in Texas, I would undoubtedly prefer crimes with less chance of confrontation.
When I worked at Best Buy, loss prevention was very clearly instructed that using force to stop a shoplifter would get you fired.
