Here are a series of  video clips  the great changes of the 1930s, where  policies what had been considered labor radicalism and by  some communism was enacted and became part of the American mainstream.   The first deals with the Scottsboro Case and the role of the CPUSA.  The second deals with Harry Bridges, a close ally of the CPUSA and the most militant left labor leader I would say in U.S. history.  The third  is Roosevelt announcing the social security act;the fourth , the high point of radicalism in the political mainstream, Roosevelt's 1936 speech, before his landslide victory, denouncing the "economic royalists" who had led the country to depression;the fifth  deals with the struggles to build an industrial union at the Ford Motor Company, which had organized its factories as a police state; the last deals with Franklin's Roosevelt's attempt to confront the issue of the Democratic party in 1938 and make the party a represenative rather than an intermediary of New Deal policies
