In the preamble to the Constitution it states We The People will "promote the general welfare." This is enshrined in public services like EMS, firefighters, and police. Pretty basic. I don't know why the government doesn't provide healthcare. This is especially prudent when the government, by it's own admission, supplies Medicare and Medicaid to old people and young people and pregnant moms. So apparently healthcare is a right, just, only a right for like 20% of the US? Only a right if you meet certain criteria?
Do you know what the Public Health Service is? It's a uniformed branch of the government that was originally a part of the Navy. The PHS was originally tasked with containing outbreaks of disease in port cities. They would go in and provide containment and medical assistance to the local authorities and populace. USPHS was created in 1798. So the US government, at some level, from as far back as 1798, has observed that healthcare is a right. It is literally nothing but fat cat capitalists and kleptocrats and their revisionist cronies that keep middle class Americans believing for some reason that not having access to medical care is somehow better than having it.
