This book is timely in view of the Temporary National Economic Committee's study of concentration of economic power and control and the wide interest on the part of the public in the fate and social importance of small business. The book, is in essence, an analysis of the effects of ""bigness"". It is based upon Brandeis' earlier The Curse of Bigness and, historically, picks up where Brandeis left off twenty-five years ago. The philosophy of the book is expressed through dramatic exposition of case histories, rather than through comment. The effects of bigness are shown in the instance of several large industries, in banking, insurance, federal and municipal government. The thesis is that size, even where it is economically to public advantage, through interference with individual liberty and initiative is destructive of important social and psychological values. The style is simple, the book easy reading and dynamic.
