Founded in 1798 to care for merchant seamen, the Public Health Service ran hospitals for 183 years. Medicare and Medicaid eroded the rationale for federal hospitals, the War on Cancer pulled money toward the NIH, and administrations proposed closures while Congress kept saving them, until a 1981 budget law closed the last eight hospitals and the Carville leprosarium. The money did not vanish but migrated to research.
Historians treat Medicare and Medicaid as a slow solvent rather than a trigger, and the idea that money migrated to the NIH is the series' interpretation rather than a line-item fact. Counts of clinics closed vary, and the starving was bipartisan.
