In "The Theory of Business Enterprise" (1904) Veblen distinguished the motivations of industrial production for people to use things from business motivations that used, or misused, industrial infrastructure for profit, arguing that the former is often hindered because businesses pursue the latter. Output and technological advance are restricted by business practices and the creation of monopolies. Businesses protect their existing capital investments and employ excessive credit, leading to depressions and increasing military expenditure and war through business control of political power. These two books, focusing on criticism first of consumerism, and second of profiteering, did not advocate change.
