| Is Wal-Mart going wobbly Over the past
couple of weeks, America’s largest company--linchpin of the low-wage, no-benefit
economy that is increasingly the norm in America--has announced some surprising
reversals of course. In a series of speeches and interviews, chief executive H.
Lee Scott unveiled four initiatives that he clearly hopes will polish the
company’s increasingly tarnished image. Wal-Mart, he said, will shift to more
environmentally responsible practices--demanding better packaging of its
products. It will offer more affordable health insurance to its employees,
cutting the monthly premium in some cases to just ＄11. It will monitor the
environmental and health and safety practices of its foreign suppliers. And it
will lobby for a higher federal minimum wage. Scott’s timing is anything but accidental. The sweatshop c A. an accident took place in Wal-Mart’s suppliers’ sweatshop B.
