I heard about that Frontline sweatpants story, but I haven't seen either the PBS spot or the Wal-Mart "High Cost of Low Price" documentary. Gotta see both of them.
On a semi-related note, I highly recommend everyone see the new documentary "Why We Fight" by Eugene Jarecki, coming out on 1/20.

I saw this last year at the Sundance Film Festival. Powerful, and I believe it comes from a more grounded perspective than documentaries of recent years (a' la' Michael Moore). He includes interviews with some stalwarts of the NeoCon movement like Bill Kristol and Richard Pearle- although his conclusions regarding the rise of the Military Industrial Complex become obviously slanted towards a "warning", it comes as close to a balanced presentation that you'll find in a documentary. (Jarecki also directed "The Trials of Henry Kissinger"- also highly recommended.)
The reason I bring this up is that it speaks to some of the most basically philosophical ideas about what kind of culture we are, and where the ends of the political spectrum are trying to drive us in the future.
