Final answer:
The provided information does not directly answer the specific question about the percentage of health care expenses covered by Canadian employers, with a focus on prescription drugs.
Step-by-step explanation:
The question asks about the percentage of health care expenses Canadian employers cover, specifically in relation to prescription drugs. The provided information does not directly answer this question, as it focuses mainly on the U.S. health care system and Medicare. However, it does mention that employers in countries with government-provided health care, unlike their American counterparts, do not bear health care costs directly, which likely leads to lower costs for prescription drugs and other health care services being passed on to the consumers or employees. To accurately answer the student's question, additional research specific to Canadian health care statistics would be necessary, which would look at Canadian governmental and non-governmental sources that detail employer contributions to health care costs in Canada.
