As the federal government debates how to wean the country from its addiction to oil, Wal-Mart just announced it would require suppliers to make major appliances that use 25 percent less energy within the next three years.
While Congress wrings its hands over higher health care costs, Wal-Mart vowed to save companies $100 million this year by processing their prescription drug claims. (It already sells generic versions of prescription drugs for just $4, well below the national average.)
記得Jared Diamond也以McDonald's和De Beers為例.
