For all those that have let themselves be convinced that war stimulates the economy,
this interview with Eustace Mullins, deemed the "most dangerous man alive" by J. Edgar Hoover because "he found out too much that people in power would prefer to remain hidden so they could continue their dirty work unhindered", underlines for whom war is most profitable and why.
"The author of such incendiary books as Secrets of the Federal Reserve, Murder by Injection, and The Curse of Canaan, Mullins was harrassed by the FBI for almost a half century, and had one of his books burned in Germany in the 1950s. These stories are recounted in one of his books, A Writ for Martyrs."
