Every three years, as part of my job, I and my colleagues get a taste of the healthcare that the British take for granted. The doctor and nurses in the medical office in the federal building who give us our 3-year medical exams are employed by the HHS - Federal Occupational Health Agency. They exhibit a degree of thoroughness and competence that I don't see in the US's private-sector "primary care provider" offices (to non-USAns - similar to GP's or family doctors) where they are constrained by insurance rules and the corporate bosses over them, and unreasonable workloads and understaffing. Adequate staffing costs money and hurts profit, you see. A Brit or even a Canadian or Australian (where at least the insurance is publicly provided) probably would not believe how dysfunctional US healthcare is until they see it.
Another taste of what medicine can look like when doctors are civil servants directly serving the people can be seen in the British TV drama Doc Martin currently playing on US PBS stations. Yes it is fiction - but the depiction of his medical practice is close to reality.
