The rate of spending for health care has outstripped economic growth in almost every country for the past 15 years. There aren't obvious ways of controlling health care costs that seem realistic. Approaches that have been considered include Universal Health Care programs, cuts in health care services, increasing taxes, entrusting more services to private health insurance companies, and adding or increasing co-payments for insurance.
Trying harder to make a system that is fatally flawed is not the answer. Wellness, prevention, and lifestyle medicine would certainly lower health care costs considerably, but the sick care system we have generates a lot of the gross national product and converting to a health care system simply would disrupt this income considerably.
