"built on the grave of a dozen former jobs"
I'm not anti-union per se, and I certainly don't view 200-odd people losing their jobs as some sort of Haw-haw moment. But there are certain economic realities that are so unavoidable that they might as well be considered laws of nature.
Before you commend or excoriate Wal-Mart for anything, I implore you to read this essay by "liberal capitalist" Evan Kirchhoff. No excerpt can do it justice, but I realize that's the custom:
Which brings us, inevitably, to Wal-Mart. Feel free not to shop at Wal-Mart -- hell, pick a reason: the creepy good 'ol boy corporate culture, the renorming of their media products for an evangelical-Christian pocket universe, the apparent see-no-evil attitude towards abusive local managers -- but don't believe that you're striking a blow for working-class wages by doing so.
I insist you read the whole thing.
