To be fair trying to predict the future is fraught with difficulties. The Bank of England yesterday again revised their prediction for the rate of growth in the UK economy. Not from a year ago but since only last November. In August they predicted the economy would grow by 0.8%, in November they increased their prediction to 1.4% now they believe the economy will grow by 2% next year. These are the experts. A change in the prediction of over 100 % in less than a year. The reality is their guess is as good as yours.
Incidentally, I think we should all recognise that whilst we may be leaving the EU we are not suddenly going to become immune from downturns in the World economy. Just as in 2007/8 if all the World’s major economies move into recession we should not assume we will be exempt.
