This book, available for free in PDF form on the Mises Institute's website, collects two complementary works by Rothbard: 1) War Collectivism in WWI and 2) WWI as Fulfillment. Rothbard discusses the idea, becoming popular with the intellectual elite in the early 1900s, that an economy should be totally planned via collaboration between big business interests and central government agencies. WWI provided the first excuse for this endeavor and is largely the genesis of the state corporate capitalism we have today. This book is an excellent supplement to the outstanding work Dr. Robert Higgs completed in Crisis in Leviathan and provides convincing evidence for Dr. Higgs' "ratchet effect" theory whereby big business interests and powerful government agencies take advantages of crises to permanently secure more power and create economic advantages for themselves at great cost to the public at large. Of course, this costly phenomenon is applauded and spurred on by central planners and corporate interests alike. I cannot do justice to Rothbard's well-researched and persuasive work with a summary here, so if this sounds interesting at all, I recommend picking it up for free from mises.org.
