We do need luxury goods. We need the artisans to keep working their craft or their skills will be lost forever. We don't all want cheap imported tat and throwaway fast fashion. The UK can't compete in the cheap sector but we can excel at high end and that should be embraced.
As for the tourist industry, how many times can one British citizen visit the Tower of London, Scone Palace, Stonehenge and all the other venues that attract the foreign visitor?
I stopped holidaying abroad years ago and keep my £ in the UK as far as possible but recognise that we need the foreign tourist income.
