<P> In the first 10 -- 15 years of the 20th century Progressivism was influencing both Europe and the United States . Many European countries were passing the first social welfare acts and forming the basis for compulsory government - run or voluntary subsidized health care programs . The United Kingdom passed the National Insurance Act of 1911 that provided medical care and replacement of some lost wages if a worker became ill . It did not , however , cover spouses or dependents . U.S. efforts to achieve universal coverage began with progressive health care reformers who supported Theodore Roosevelt for President in 1912 , though he was defeated . Progressives campaigned unsuccessfully for sickness insurance guaranteed by the states . A unique American history of decentralization in government , limited government , and a tradition of classical liberalism are all possible explanations for the suspicion around the idea of compulsory government - run insurance . The American Medical Association ( AMA ) was also deeply and vocally opposed to the idea , which it labeled `` socialized medicine '' . In addition , many urban US workers already had access to sickness insurance through employer - based sickness funds . </P>
