[1] Early in his career, Lundberg was a business reporter for United Press International, and the Chicago Daily News.

[1] Described by the Los Angeles Times as "witty, articulate, opinionated, marvelously well-read and not the least bit shy about telling us exactly what he thinks about America and the mess we've made of it", Lundberg was vocal in his contrarian viewpoints, describing the United States as an oligarchy, eviscerating prominent American families including the Rockefellers and Hearsts, and denouncing the United States Constitution while calling for its replacement with a parliamentary system.

The Rich and the Super-Rich documents and examines the extreme concentration of wealth in America that places above half of all assets, and overwhelming control, in the possession of 2.5% of the population, largely by inheritance.

[7] According to the music critic Robert Christgau, the O'Jays' song "Rich Get Richer" (from the 1975 album Survival) was based on Lundberg's writing.

[8] In addition to his journalistic writing, Lundberg also spent 16 years as an adjunct professor of social philosophy at New York University.
