"In business, Wal-Mart is cited as an example of a successful principle-centered organization."

you gotta be kidding! Wal-Mart, an enormous corporation, is known for its exploitative business practices all over the world! they undercut prices by slashing employee benefits and forcing factories world-wide that manufacture goods for sale in their mega-stores to cut costs by creating slave-labor type work environments for their employees; if a company can't cut costs enough to suit Wal-Mart, then Wal-Mart takes their business to another 3rd world country that is willling to pay their workers less under increasingly harsh working conditions in order to keep costs for the consumer lower than the competition.

I have never shopped at Wal-Mart and I never will.
Shame on the author of the book you are touting to use Wal-Mart as an example of "principle-centered" business!!
