"Single payer" is a system that replaces multiple private health insurance companies with a single public agency - like an improved Medicare-for-all program.
It will cost far less than what Americans are paying now to private insurance companies - and provide more comprehensive care.
It will cover all medically necessary goods and services, including preventative care, hospital stays, mental health, reproductive health, dental and vision, and prescription drugs.
Health care providers will remain private and they can go back to providing care instead of doing insurance company paperwork.
A national single payer program would be best, but Canada's nationwide program started in one province, Saskatchewan. America's single payer system could start in Rhode Island!
