What is the author's style in The Theory of the Leisure Class by Thorstein Veblen?

The book is written from the point of view of economics and sociology. It is a study of the different classes of society and how they developed and evolved due to changes in economic forces. Veblen examines the economic characteristics of the leisure class and determines why they do the things that they do and how they affect the rest of society and its progress. He employs a Darwinian approach to his analysis, which adds to the humor and satire.
