May I recommend a couple of Best-Selling Books that would make good Christmas gifts for the discerning ‘Austrian’ non-interventionists on your list, as found at LewRockwell.com/ :
Fascism vs. Capitalism, by Llewellyn H. Rockwell, Jr.
Freedom Betrayed: Herbert Hoover’s Secret History of the Second World War and Its Aftermath, by Herbert Hoover and George H. Nash.
The former author’s website, LewRockwell.com/ bills itself as the most popular libertarian website in the world.
Mr. Rockwell used to work for former Texas Congressman Dr. Ron Paul, and this is his most recent Austrian economic analysis on Capitalism versus Fascism, yet another scholarly book in the Hayek-Mises tradition.
Mr. Hoover was the foremost non-interventionist of his day (as Dr. Paul is in our day), and his huge oeuvre is eye-opening, and available for borrowing from the Oak Bay branch of the Greater Victoria Public Library system.
