"What, on the eternal list of priorities, precedes health? What more obvious role could government have than the defense of the life, of each citizen? We cannot stop every germ that seeks to harm us any more than we can stop every person who seeks to harm us. But we can try dammit and government's essential role in that effort facilitate it, reduce its cost, broaden its availability, improve my health and yours, seems, ultimately, self-explanatory."
