The book is a classic, when it comes to describing the modern economic, sociological and psychological makeup of society in spite of being first published in 1899. It can still be used as a guide to all those sciences, as well as a good introduction into where and how marketing / advertising can work / appeal.
The authors starts with the gender role evolution (a similar, more modern text on the same subject, which might be an easier read is Jared Diamond's
Science Master: Why Is Sex Fun? The Evolution Of Human Sexuality (Science Masters)) and then traces the development from the early, relatively undifferentiated society to the more modern, stratified one, characterised by the pecuniary (leisure) class on the one hand, and the industrial one on the other. The author then proceeds to show the role of dress, conspicuous consumption, leisure time, sports, institutions, religion, animism (aka luck), as well as education in strengthening and maintaining the system, always relating back to what developmental aspects lead to their development.
It makes for fascinating reading, both in terms of the clarity of thought the author applied, as well as how modern the work still is content wise, and how applicable to today's society, over 100 years after the book was first published. The evolutionary perspective, as used by the author, took a long time to be used so insightfully and comprehensively in social science research by others later on in the 20th century.
On top of that the work exudes a certain wittiness / sarcasm, which is not really apparent in a phrase or sentence, but comes across in the overall feel of it. There are no laugh out loud moments here but there will be a twinkle in your eye after reading a chapter.
The final comment I'd like to make about it is the writing style - this is the only aspect of the book, where the publication date is clearly apparent. It is relatively heavy going, with a rich but ponderous language (Veblen is no Stephen Fry), long sentences, no attempts at signposting, or introducing and concluding chapters, or for that matter, the book. It is not a commuting, holiday, or goodnight read, it does require one to apply oneself to it a bit more thoroughly.
