In his book "Film in the Battle of Ideas", Lawson wrote that "the rulers of the United States take the film very seriously as an instrument of propaganda" and said they believed that the influence of Hollywood movies was used to "poison the minds of U.S. working-class people". He believed that was inaccurate about U.S. working-class life. Lawson wrote that Hollywood "falsifies the life of American workers" and its "unwritten law decrees that only the middle and upper classes provide themes suitable for film presentation, and that workers appear on the screen only in subordinate or comic roles." According to Lawson, "workers and their families see films which urge them to despise the values by which they live, and to emulate the corrupt values of their enemies" and "the consistent presentation on the nation's screens of the views that working-class life is to be despised and that workers who seek to protect their class interests are stupid, malicious, or even treasonable" is what Hollywood engages in.
