Unity never comes easy and 'Brexit' may well be taken as an example. The European Union was born as a result of the World War II and after about seven decades of the post-war era now Britain wants to beak way from the twenty eight member bloc. But, with the country's exit, Britain is not the only one to face the consequences. As a whole, E. U. is facing an existential crisis.
It is true that Brexit brings a risk of 'capital flight' from the UK and the fear rightfully strikes residents, officials and governments.
Times when people rush for exit there are chances of banks collapsing and the currency dropping as most people do what is rational and that is to join the queue.
