The US health care system is characterized by high technology and research but also lacks standardization and coordination. It employs millions of professionals across thousands of facilities but access remains unequal and costs are rising faster than economic growth. The system has evolved from early traditions of home care provided by women and religious healers to the current complex arrangement involving private insurers, employers, and government programs. Ongoing debates center around whether health care should be viewed primarily as an economic good or a social right.
