Walmart is selective about what it sells—refusing, for instance, to carry music or computer games with mature ratings, magazines with content it considers too adult, or, in some of its stores, handguns. Because of its sheer size, these decisions can become influential on the culture. Do you think this is a positive or negative effect of the growth of this retailer? Why?

As the largest company in the world, with more than a million employees worldwide and more than $400 billion in sales in a recent year, Walmart has become big and powerful enough to infl uence the U.S. economy.
