Medicare was born in Saskatchewan, but its roots are global. Radical Medicine offers a thrilling new history that connects the history of socialized health care in Canada with the New Deal in the United States, the October Revolution in Russia, and the British Labour movement. It weaves together the histories of brillitant international health advocates, insurgent social movements, and intense political conflicts. It shows how, while medicare was shaped fundamentally by local forces and cultures, we can only understand its history in a world-historical context. As universal public insurance programs crumble, Radical Medicine is the medicare book we need now.
