The large number of uninsured creates a significant strain on the emergency medical system. For-profit managed care has shown a steadily increasing pattern of denying needed treatment. More Americans are dissatisfied with the health-care system overall. Overhead costs are significant. In an October, 2003 Washington Post/ABC poll, by almost a two-to-one margin (62 percent to 33 percent), Americans said that they preferred a universal system that would provide coverage to everyone under a government program, as opposed to the current employer-based system. Both the French and Canadian systems rank in the Top 10 of the world's best health-care systems, according to the World Health Organization. The United States comes in at No. 37. The rankings are based on general health of the population, access, patient satisfaction and how the cares paid for. Although America is advanced in medical technology and is ahead of other countries our system is not working out.
