Re "Profit margin"(Public Forum, Aug 6):
The free market is the only thing that works. Yes, even in health care, it works.
Although when an emergency occurs, it is not the time to shop around for a good price, the benefits are still realized. Hospitals do not live off of emergencies alone. They spend plenty of time servicing less urgent needs and every time they make such services cheaper, their emergency care is sure to follow.
