The main subject of this book is that Britain has been in decline for over one hundred years and that decline was inevitable.The book suggests that until the government of Margaret Thatcher there was no sign of the decline being solved, as although the political elite of the last hundred years were aware of the decline the policies they implemented seemed to have no effect in stopping it.Another point the book debates is what the Thatcher era really was.Was it the response which brought decline to an end or was it just the last chapter in the episode of the hundred years decline? The book was written to underline how and why Britain declined,to show how decline had been defined and explained,and to examine the various political strategies used to tackle the decline.
