US private health insurance companies are a useful component in the ecosystem of health care provision. They only exist to enrich themselves and are built to continuously increase profit for their shareholders which means delivering the least amoung of health provision to their customers. A single-payer system would enhance healthcare access, and it would be significantly less expensive, simply by eliminating the unnecessary middle-man that is private health insurance. It’s that easy for the USA.
