It was a typical British reaction.... they were never really part of the EuroZone anyway..... You talk about those who invented the modern concept of Commonwealth and Multiculturalism (cultural ghettos)... Never seen more racist than a ''white british'': You can come here, make commerce, but you'll never mix with us or be one of us but thanks for the money.
So obviously, they joined the EuroZone without taking the Euro, keep their money etc.....
Also, you see the generation divide... the ''leave'' was a majority in the 45+ age group
Bonus: I am making money on the market fall and pounds (Canadian dollars look good now to take Euro shares)
Long term issue: Scotland and Ireland will push to seced from Great Britain and join the Euro, English elites will be happy in their castle and writing new laws, Germany/France duo will do everything to alienate Great Britain, Russia will start selling gaz cheaper.
Who will benefit from the change? Tourists, Right-Wing politicians, Russia
