The giant retailer's low prices often come with a high cost. Wal-Mart's relentless pressure can crush the companies it does business with. (...) The real story of Wal-Mart, the story that never gets told, is the story of the pressure the biggest retailer relentlessly applies to its suppliers in the name of bringing us "every day low prices." It's the story of what that pressure does to the companies Wal-Mart does business with, to U.S. manufacturing, and to the economy as a whole. WalMart, (known as ASDA in the UK) is a controversial American Supermarket chain. Their supporters say they are popular and efficient. Opponents say they exploit workers. WalMart is accused of Predatory pricing. That involves lowering prices in the short term to drive competitors out of business. Later when competition has gone it is alleged that WalMart raises prices to the detriment of consumers. The large WalMart supermarkets cause Traffic congestion and Traffic pollution.
They say Walmart isn't too keen on Free speech either.
No one wants to end up in what is known among Wal-Mart vendors as the "penalty box"—punished, or even excluded from the store shelves, for saying something that makes Wal-Mart unhappy. (The penalty box is normally reserved for vendors who don't meet performance benchmarks, not for those who talk to the press.) "You won't hear anything negative from most people," says Paul Kelly, founder of Silvermine Consulting Group, a company that helps businesses work more effectively with retailers. "It would be committing suicide. If Wal-Mart takes something the wrong way, it's like Saddam Hussein. You just don't want to piss them off."
