So says Adam Posen, of the Bank of England's Monetary Policy Committee.
What he really means is that the City of London would be much worse off, of course. Britain could not really be much worse off, after all. Increasing unemployment, a demoralised youth, collapsing social and health care, collapsing education, collapsing manufacturing, collapsing infrastructure and an inexorable descent into full scale dictatorship - the list is unending.
This nation has no idea where it is going in the next fifty years. There is no optimism for the future; no grand plan or pioneering spirit.
Mr Posen's view of reality may not reach much beyond his own bank balance. I can only view this man and his ilk as a barrier to the future prosperity of this nation and its inhabitants.
