Criticism of Wal-Mart (NYSE:WMT) is nothing new in Fooldom. The company is so big and so important that -- love it or hate it -- it's hard to ignore. Here are just a few of many recent articles:

Of course, we're not the only ones paying attention. At Adrants.com, I recently read an interesting opinion that Wal-Mart is "wasting" $35 million on a campaign to promote its "Acres for America" initiative, whereby it's preserving an acre of land for every acre it develops. This sounds like a noble enough effort, but more details are needed. For example, Wal-Mart presumably seeks out prime locations for its stores. Where are these acres it's preserving? Are they acres we'd really want to preserve, or acres that nothing can grow on?

A little digging turned up some details. The project is in cooperation with the National Fish and Wildlife Foundation, the preserved acres will be wildlife habitats, and the $35 million will be spent over 10 years. Total acres to be protected are estimated at 138,000. (Interestingly, Wal-Mart appears to develop some 5,000 acres annually these days.)

The Adrants.com opinion, though, focused its attention elsewhere: "If Wal-Mart simply allocated that $35 million to payroll, it would make great strides towards solving at least half its problems." This reflects some ignorance of just how big Wal-Mart is. It actually has some 1.6 million employees (er, "associates"). Divide that $35 million among them, and they'll each get a whopping $21.88. I fail to see how $21.88 will make great strides toward solving half the company's problems. Unless, of course, the firm's problems can be valued at, say, $40 per worker. In that case, a mere $64 million, or roughly 0.62% of its net income for the year, would solve its problems. If that's all it would take, I think Wal-Mart would have taken care of these issues long ago.

The issues Wal-Mart faces are kind of big and can't be easily solved. It has come under attack for allegedly putting mom-and-pop businesses out of work, treating employees unfairly, and more. But the firm is trying to do some good, along with delivering low prices to consumers. It does engage in a lot of charitable giving, and it wants people to know about its good work.
