John Tierney, always eager to make himself look like an asshole, argues that Wal-Mart - by beneficently purchasing the wares of underpaid factory workers - has done more to alleviate poverty than Muhammad Yunus and his Grameen Bank ever did. I'd hold it against him, but I think he was just trying to start a fistfight with Paul Krugman.

(To be fair to Tierney, that summary slightly bastardizes his argument. But to be correspondingly fair to me, Tierney bastardized economics before I bastardized Tierney.)
