That something happens over a long time does not mean that it does not have several causes. I can remember well how the UK promoted the 'service' and 'finance' industry in the past decades. Manufacturing was seen as obsolete. Especially when North Sea oil brought wealth to to Britain for some time, they were mostly busy managing and consuming this wealth - currently oil is cheaper and North Sea oil is less competitive.
