What country stands out as being a developed country where private individuals are required to pay the majority of health care?

The correct answer is the United States of America.

The United States are known for not having widespread and universal health care. Medical services are paid mostly through insurance or through direct payments for services. This stems from the individualistic and self-reliant philosophy of the United States where the citizens have the freedom to pay for what they want. Same goes for the health care system.
