"Wal-Mart: The High Cost of Low Price"
According to this New York Times story (registration required), Robert Greenwald, the producer/director of "Outfoxed: Rupert Murdoch's War on Journalism," is on to his next documentary, this time exposing the ills of retail behemoth Wal-Mart which, according to him, employs 1.5M and opens a new store each day (with 3500 stores already in place):
Their plan is to depict what they and a growing number of critics perceive to be Wal-Mart's sins against society: unfair competition and erosion of the fabric of communities; exploitation of its American workers, and of the government welfare programs many rely on to supplement their wages and benefits; union busting; reliance on suppliers with sweatshops overseas; and environmental negligence - among others.
They also intend to show how the retailer exerts its outsized influence on American culture through the so-called "Wal-Mart effect," by limiting the choices of products like clothing, music - and movies - that are available to consumers.
