Walmart recognizes what's coming down the pike: inflationary (in the best sense) economics. The labor market's gonna tighten like Mitch McConnell's a$$hole when presented with a stimulus bill, and the Confederate Party race to the bottom economic shyt is starting to be shown the door.
Hopefully this means the 15 an hour movement is far from over, because until labor starts getting some of its power back, the corporate powers are going to be a continuing threat as they slide more money back to the right, doing their "playing both sides" fukkery again.
You'd think they've learned by now that the Republicans' "Socialism for the rich" and total deregulation and kneecapping of the social safety net is a dead end and a threat even to them but, no. All they prolly care about still is next quarter.
