Please don't mislead readers with false information. The original NYT title does not have the word "profits" in it:
"How Did Walmart Get Cleaner Stores and Higher Sales? It Paid Its People More"
This is a critical distinction because the details of the story actually explain that profits are down -- not up -- after paying their workers more:
>The profit landscape is less sunny. Operating income for Walmart’s United States stores was down 6 percent in the most recent quarter, reflecting higher labor costs and other new investments.
>In the short term, the Walmart experiment shows pretty clearly that paying people better improves both the work force and the shoppers’ experience, but not profitability, at least not yet.
