While I still hope Brexit is shelved, I also hope that the EU reforms, and hopefully adopts a better overall monetary and fiscal policy, that will in turn address imbalances across Europe as a whole.
I think it is right that the UK within the EU retains its Sterling (GBP) and the Bank of England's role; Just as I think it is right (and more economically viable) for the role of the European Central Banks to allow, facilitate fluctuations tailored to and within each EU member State (by their individual Governments) and even regionally across the current Euro-zone itself.
Whereby, Regional measures in Harmonious Quantitative Easing may stimulate growth in specific Regions, revitalizing their economies from within, as each Regional GDP improves (with falls in unemployment and increasing tax surpluses to honour EU contributions and any debt repayment).
In my thinking austerity is dead, while stimulating growth in Regional and Local economies from within themselves is vital, as it bolsters Community spirit and self sufficiency in a positive way; Where peoples can flourish, without being reliant upon handouts, unaffordable loans, the need to migrate, or God forbid, the turning to crime in order to physically survive.
Harmonious Quantitative Easing, The introduction or injection of cash bonds into a Regional / State Economy within certain Agreed Limits, to avoid any major adverse effect upon other International Trade Agreements, Exchange Mechanisms and the overall Global Market.
