Why Wal-Mart will rule the world

Fascinating Fast Company article explains why manufacturers must suck up to Wal-Mart's demands, or face extinction.
For many suppliers, though, the only thing worse than doing business with Wal-Mart may be not doing business with Wal-Mart. Last year, 7.5 cents of every dollar spent in any store in the United States (other than auto-parts stores) went to the retailer. That means a contract with Wal-Mart can be critical even for the largest consumer-goods companies. Dial Corp., for example, does 28% of its business with Wal-Mart. If Dial lost that one account, it would have to double its sales to its next nine customers just to stay even."
