Yeah, we can look at anecdotal "evidence" or we can look at the fact we are spending much more than Canada on health care and getting worse results.
Canadian health care system probably has problems just like any other one, but our health care system is fundamentally broken and headed for chaos, and making America uncompetitive. How many hospitals have closed because we don't pay for preventative and nonemergency care, and force them to treat people in the ER? How many jobs have been shipped overseas because of huge health coverage costs on employers? How many businesses don't get started because would be entrepreneurs decide to stay at their current jobs because they can't afford to lose their health coverage?
