This book reviewer says the 1930s were, on the whole, a pretty good time to be British. It is a point of view one does not come across very much, that is for sure. The stock image of the 1930s is the era that saw the rise of the Nazis, the Great Famine in the USSR, the Great Depression, Roosevelt, the Royal Abdication Crisis, etc. But was there more to it than that, at least at home? The book says that British society was in some ways in pretty good shape.
In military terms, at least by the end of the 1930s Britain had evolved what ultimately proved to be a very well organised air defence system, with radar and nifty fighters like the Spitfire. The 1930s was stylistically elegant: the cars of that era looked absolutely glorious.
On the other hand, I would argue that the 1930s was a period in which limited government continued to be under siege and apostles of planning and greater government regulation were gathering momentum, to reach fruition – if that is quite the right word – in 1945 with the election of the Attlee Labour government.
