One thing that I am reminded of in the current zeitgeist with respect to capitalism and democracy is the 1930s and its condemnation of democracy as outdated and how fascism was the progressive way forward.
It might actually be, but we won't find out any time soon. Nazi Germany put such a stain on fascism, it will be quite a while before it is taken seriously.
Unfortunately not; the most recent book I read on the period was Gathering Storm, by W. S. Churchill (not the most unbiased observer, but very engaging reading).
