Government spending on health is essential for the accessibility and sustainability of healthcare services and programs.

For those people who would otherwise go without care due to lack of financial means, any quality care is an improvement.

Since people perceive universal healthcare as free (if there is no insurance premium or co-payment), they are more likely to seek preventive care which may reduce the disease burden and overall healthcare costs in the long run.

Single-payer systems reduce wastefulness by removing the middle man, i.e. private insurance companies, thus reducing the amount of bureaucracy. In particular, reducing the amount of paperwork that medical professionals have to deal with for insurance claims processing allows them to concentrate more on treating patients.
