Empires are not economically and morally viable anymore, the UK did incredibly well in other sectors. This country flourished when it invested in R&D and finance, and the wealth generated by this was the engine that carried everybody else along.
This has changed lately and the result is a stalemate which can be even more dangerous if not addressed on time.
I believe the UK should stay well out of the Eurozone, but should really work better when it comes to economic interactions. The stupid naysaying attitude of this government and clowns like Farage aren't doing us a great deal of good
