The biggest problem is that the decision will be made by people who have little interest in and knowledge of the subject except for their nationalistic values and pride being displayed.
Most people are unaware of what the EU does and has done for the UK in decades gone by, some were not even born then, let alone learned about it in their history books.
IMHO:
- Should a Brexit happen: No!
- Should UK regain some of its lost (financial) independence: Yes, like most other countries would like to, but in this the UK is different in effect with its sovereign economy which should remain intact, it is healthier then the Eurozone and provides a stimulus to it being closely linked.
- Should UK get more control over their benefit system funds given to non-domestic persons: Yes, as it is not fair to receive UK money (for instance for a child not living ik UK but elsewhere in EU and receiving benefits to the amount of those given to UK parents to raise their offspring in UK) when not abiding there; benefit should be paid, by UK if legally required, but only to the national rate set where the child is brought up and resides.
- Would the economy suffer as a result of induced costs as a result of a Brexit: Yes, it will cost many millions to rewrite all legal documents, manuals, jurisdiction, treaties, etc. A waste of UK resources bar to those in the business of rewriting them.
But this forum is about aviation, it seems impossible to imagine airlines closing and moving operations but in today's theatre of daily pan-EU flights nothing should be dismissed. The workforce is the probably the biggest loser in this game, set to accept changes or to be told "or else..."
