Is patriotism dead

Is patriotism dead. Does it still have a place in a multicultural world. 

Can a country feel, first and foremost for itself, or has the diversity within a nation made this impossible. Can the subliminal values which make up the recognisable character of a country and its people, ever be supplanted in an environment with such a kaleidoscope of competing interests.
The substance, "character" is formed by the surety you have of people responding in a similar way to crisis. The "stiff upper lip" is an example of the English reticence to show emotion for instance.
Living in an environment which has become so changed by the huge influx of people from all parts of the world, each with their own characteristics, can a 'nation state' still  exist any more. Is the concept of a national image an anachronism in this day and age. Do values which used to denote a nation now mean little, lost in the mish mash of a new
construct  more in line with an arbitrary need for people, of what ever creed or conviction. Part of the economic plan hatched in far away boardrooms by faceless executives who themselves have no fixed nationality.

Is this "Brave New World" a world of fact or fiction. Has fiction become fact, with all the terrible consequences which Huxley's description of a society 'manipulated' in all and every way revealed.

Do we have any way of reversing the trend or are we all destined to become only 'numbers', part of an action plan to smooth the social desire for self recognition, with a pleasure seeking alternative administered by a Commission.
Is Brexit the last chance to dig down and rediscover our real needs, to evaluate what is important, to have an input. If it is we have to be willing to be creative and stop being led by the nose like donkeys. We have to take an interest and stop assuming others have our interests at heart.
With a dose of austerity perhaps the impossible will happen and we will ween ourselves off 'free loading' through necessity, since we don't seem to have the stomach to do it any other way.
This not only includes weaning the under class, which will find itself ever more marginalised but also the upper class who will have to be dented its traditional paternalism.  Making the sanctified regions of  Public service such as the civil service and the armed services  for example, much more accessible to the ordinary people in society.
Ban the links through family and patronage. Make it impossible for people to be appointed simply through the act of knowing someone but only through the rigour of being the best person for the job, measured through real merit.
Perhaps a Brave New World would be no bad thing, so long it was tested democratically (proportional representation) by an educated savvy public opinion.
