The disparity in wealth in this country is matched only by the disparity in health coverage. Neither come anywhere close to fair, and both leave a huge number of Americans poor and getting poorer, sick and getting sicker.

Robert Greenwald, the prolific social issues documentarian, responds to this crisis with "Sick for Profit," a short film that exposes the bank-breaking tactics of one of America's largest insurance companies.

Stephen Hemsley, the CEO and president UnitedHealth Group, says that his company is dedicated to helping people lead healthier lives. But many of the people who have United plans have met with one obstacle after another in trying to file their claims; meanwhile, Hemsley earned $3.2 million in 2008, despite being implicated in a lawsuit against UnitedHealth last year.

Greenwald and his company, Brave New Films, may take on similar topics as Michael Moore, but his approach is far less heavy-handed. He relies on testimony, facts, and good old-fashioned reporting. In the end, Greenwald's films are true documentaries, not mere propaganda.
