Actually, I'm not by any stretch of the imagination convinced that Wal-mart is a highly profitable corporation by any long-term measure: that is, I'm quite convinced (probability greater than 0.99) that Wal-mart is sacrificing long-term growth and sustainability in favor of superficial short-term gains. Upper management is desperate to do anything to make the stock price budge, long term be damned. Eventually, this superficiality will expose itself as the house of cards it truly is.

The recent news regarding firing over 10,000 employees at Sam's Club is salt in the wound here. You don't cut employees if you plan to proactively expand your business, you cut employees to entrench yourself and react defensively to the market moving around you. You especially don't cut your marketers and salespeople (which is what those people giving out free samples are... err, were... functioning as). You might shift a slice of your labor budget from a less effective strategy to a more effective one, but you don't simply drop the slice entirely and pocket the change. That will destroy the business, even if it pads the golden parachutes on the way out.

And it's not like the job cuts are the only piece of evidence. Apparently, in the few years its been since I worked there, they've stopped hiring full-time employees entirely: now, all hires are part-time. Thus: second-rate health insurance (not that health insurance ought to come from employers in the first place), no retirement plan (not even the crappy Wal-mart stock they pawned off on full-time employees like me), and easier to fire people on a whim. But this has the hidden cost of needing to re-train people from scratch as the n00bs enter the revolving door, and it also sabotages the quality of labor by destroying any sense of loyalty to the company or enjoyment of the work environment. They then respond to falling labor quality by trying to wring even more out of the employees they have, creating a downward vicious spiral as the best employees walk out the door for greener pastures.

If I had any substantial amount of money invested in Wal-mart (i.e. beyond the pittance of stock accumulated in my 5 year employment, almost too trivial to bother with), I would be pulling it out now for saner investments.
