I've never come across a similar claim so I'm not sure I can answer that but in terms of the second half of your question I am not sure that the inter-war period in Britain can be seen as one of structural change specifically because of the British desire to remain an imperial power and maintain (what they thought to be) the position as the Third World Power. Furthermore the Second World War would point towards the fact that Britain, behind the propaganda and facade of victory was found wanting in respects of industry. If we use Britain's lack of industrial might during WWII we can assert that for the most part society lacked both education and training and did not have the technological base of their German counterparts. This was then emphasized by the lack of investment in capital goods in the British economy as the governing elite focused more on maintaining the myth of empire. I think you will find Correlli Barnett's Collapse of British Power and The Audit of War: The Illusion and Reality of Britain as a Great Nation helpful in dispelling these arguments that the British interwar economy was not as bad as it has a reputation for.
