I enjoyed your review Mr Denman, but found it's comforting implication that "fear of change and the future is nothing new" rather misleading. I suggest that for Europe's inter-war population, fear of the future was very sensible indeed. That generation had already suffered some 20,000,000 casualties in the trauma of World War One and could clearly see they were facing another fratricidal slaughter in their immediate future, which could only be even more costly/destructive in human life and national wealth!
If you were facing the very real possibility today of some 50,000,000 fellow members of your society being massacred, some 30% of the industrial plant/housing stock being destroyed, of hunger/famine etc... being deliberately inflicted upon you and your family for years, would you not have good reason to be anxious?
When looked at from this perspective, the answer is obvious and I further suggest that our own era's feelings of unease on issues such as nuclear power/weapons proliferation, racial/religious hostility, enviromental degradation etc..... are equally well grounded in reality. The only real difference between then and now is that we know how the 1930's ended, whilst the tensions of our own era have yet to play themselves out.
