I couldn't explain it, but I would assume it was somehow associated with the whole "Walmart/FEMA camp" thing. IOW, Walmarts are something more than big boxes from which to sell you cheap shit from China.

At the first level, "They" are trying to erase hard-working and lucky country bumpkin Sam Walton's background. it's not well-known and has been erased from his wiki, but we can still find this in his Geneastar page:

Soon afterwards, Walton joined the military in the U.S. Army Intelligence Corps, supervising security at aircraft plants and prisoner of war camps.

In fact, you can see that the text was originally cribbed from directly from wiki, but wiki dropped the "prisoner of war" angle as being too much of a bullseye to hand to conspiracy theorists.

At a deeper level, the whole Walmart thing ties back very quickly to the "Salem Witches" I've done so much research on. That is, Walmart and the "world's richest man" and all that are way out on their periphery, just another project among many.

Given that, I'm not really surprised to see anything.
