What do you believe is the purpose of hospitals, clinics, and medical personnel, i.e., health care?
Too broad. That varies drastically from institution to institution. You need to be
much more specific than that. That question illustrates you lack of knowledge on the subject matter (and your immaturity). For instance:
St. Jude's
hospital provides healthcare to children at no cost to the families. They operate on fundraising.
The Cleveland Clinic
hospital on the other hand charges a lot of money but uses those profits to conduct some of the most advanced research in the world to advance the healthcare industry and save lives.
Both hospitals but each with a vastly different focus and goal. It is clear in your mind the answer was "to help people" or "to cure people". You have the simplistic (not to mention inaccurate) views of a small child. Would you like to continue? I'm willing but it seems as though this will be a
painful exercise due to your lack of knowledge about the topic.
