A recent survey found that 70% of the 1,000 Canadians interviewed thought their healthcare system was working well and that 82% believed it was superior to the system used in the United States. But Michael Rachlis, an advocate of public healthcare who is a physician and adjunct professor at the University of Toronto, said that the public's enthusiasm for the system was, in itself, a problem: "Because medicare has been so popular, it's been difficult to change it, even for the better," Rachlis says in this blog item from the New York Times, referring to Canada's public health system.
