Two things to amplify:
- There's an economic corollary to the German situation of the late 1920s-early 1930s where the young's radicalism was funded by the social order. Hyman Minsky's financial instability hypothesis seems to be proving itself. It's been popularized in the WSJ as "stability breeds instability", that during periods of stability, people don't value risk appropriately. Risk-taking behavior increases to inappropriate amounts, and financial structures tend towards Ponzi schemes. This eventually collapses as risky structures take each other and everything else down.
- I can't find a reference, but I saw a history channel show about a British woman who made quite a name for herself in telling people that the British version of Mein Kampf was severely abridged. It was in the mid-1930s, and she had a seat in parliament. The British version took out his roadmap, among other things.
