How our Marxist faculties got that way: In the 1970s, President Richard Nixon ended the war and Congress ended military conscription. So the Marxist anti-war activists -- activism is now a full-time profession -- had to do something else. Most of them went to work in the real world. But a meaningful number remained in school and opted for academia, especially the humanities and the social sciences. If they got a Ph.D., they might even become university teachers, and many of them did. They then climbed academia's ladder, rising from instructor to assistant professor, from assistant professor to associate professor, and from associate professor to full professor. These last two ranks usually carry tenure, which means a guaranteed job until one decides to retire or is fired for raping little children in the streets.

UW Madison Havens Center: Michael Burawoy has studied industrial workplaces in different parts of the world -- Zambia, Chicago, Hungary and Russia -- through participant observation. … No longer able to work in factories, most recently he has turned to the study of his own workplace – the university – to consider the way sociology itself is produced and then disseminated to diverse publics. Over the course of his research and teaching, he has developed theoretically driven methodologies that allow broad conclusions to be drawn from ethnographic research and case studies. These methodologies are represented in Global Ethnography a book coauthored with 9 graduate students, which shows how globalization can be studied "from below" through participation in the lives of those who experience it. Throughout his sociological career he has engaged with Marxism, seeking to reconstruct it in the light of his research and more broadly in the light of historical challenges of the late 20th and early 21st. centuries.
