John Ehrenreich

John Ehrenreich is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand John Ehrenreich rather than just read about it. In short: John Ehrenreich (born February 20, 1943) is an American clinical psychologist and social critic, who has published books on health policy, humanitarian policy, US history and US social policy. He is known for his development (with his then-wife, Barbara Ehrenreich) of the idea of the "medical–industrial complex" and the concept of the "professional–managerial class".

Key takeaways

  • John Ehrenreich belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect John Ehrenreich to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of John Ehrenreich from memory before moving on to harder problems.

Reference excerpt

John Ehrenreich (born February 20, 1943) is an American clinical psychologist and social critic, who has published books on health policy, humanitarian policy, US history and US social policy. He is known for his development (with his then-wife, Barbara Ehrenreich) of the idea of the "medical–industrial complex" and the concept of the "professional–managerial class". His book, Third Wave Capitalism: How Money, Power, and the Pursuit of Self-Interest Have Imperiled the American Dream (Cornell University Press) was described by Washington Post columnist E.J. Dionne as "a brilliant take on what ails our society and our politics," and by Arlie Hochschild, author of Strangers in Their Own Land, as "a fascinating 'long look' at America.... Sobering, startling, important―a big-think book." His latest book is The Making of a Pandemic: Social, Political, and Psychological Perspectives on Covid-19 (Springer).

Life and work Born in Philadelphia, Ehrenreich received his bachelor's degree in 1964 from Harvard College, followed by a Ph.D. in cellular biology from Rockefeller University and a second Ph.D. in clinical psychology from the New School for Social Research. He was a professor at the State University of New York at Old Westbury, first in American Studies, later in Psychology. He retired from Old Westbury in 2018. In 1967, Ehrenreich married fellow Rockefeller University graduate student Barbara Alexander, now better known as social critic Barbara Ehrenreich (author of the 2001 best-seller Nickel and Dimed). Together, John and Barbara Ehrenreich played a leading role in the anti-Vietnam War movement in New York City. They co-authored several books and articles, including Long March, Short Spring: The Student Uprising at Home and Abroad (1969), The American Health Empire: Power, Profits and Politics (1970), and two articles on The Professional-Managerial Class (1977). Although the pair divorced in the late-1970s, John and Barbara Ehrenreich continued to author occasional articles together, including an updating of their previous work on the professional managerial class, Death of a Yuppie Dream: The Rise and Fall of the Professional Managerial Class (2013), and The Making of the American 99% and the Collapse of the Middle Class (2011). John Ehrenreich has also published several other books, including The Humanitarian Companion: A Guide for International Aid, Development, and Human Rights Workers (2005); and Managing Stress in Humanitarian Workers (Ed., 2012), The Altruistic Imagination: A History of Social Work and Social Policy in the United States (1985), The Cultural Crisis of Modern Medicine (Ed., 1978); and The Making of a Pandemic: Social, Political, and Economic Perspectives on Covid-19 (2022) In addition to his books and journalistic writing, Ehrenreich has published numerous articles on social policy and psychology in scholarly and professional journals, including Understanding PTSD: Forgetting Trauma (2003), Managing Stress in Humanitarian Aid Workers (2004); Women in prison: Approaches to understanding the lives of a forgotten population (with S. McQuaide, 1998) and Personality Theory: A Case of Intellectual and Social Isolation? (1997). Ehrenreich has served as a consultant to NGOs in Bosnia, Turkey, Jordan, Sierra Leone, as well as in Europe and the United States. He is an International Associate of the Netherlands-based Antares Foundation.

Family Ehrenreich has two children from his marriage to Barbara (Alexander) Ehrenreich: journalist, law professor, and national security expert Rosa Brooks and journalist and novelist Ben Ehrenreich. In 1987, he married social worker Sharon McQuaide, with whom he has one child, Alexander Ehrenreich.

Worked examples

Example 1 — a first encounter with John Ehrenreich

Start with the simplest possible case. Write down what John Ehrenreich claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to John Ehrenreich before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about John Ehrenreich ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of John Ehrenreich

In research
John Ehrenreich appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses John Ehrenreich in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
John Ehrenreich is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1943 births, 20th-century American Jews, 20th-century American non-fiction writers, so understanding it makes those chapters shorter.
In everyday life
Look for John Ehrenreich outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
