I totally agree with hkAlone and Ww comments regarding the economy. Brexit is a gamble.
But I'm more scared of staying in Europe. If the current population trends continue. Something like an extra 30 million people will be living in the UK in my life time. The U.K. is already full. Public services can't keep up with demand. They are concreting over any grass they can find. Etc....
At present the UK has a trade deficit with Europe of around 70 billion pounds. It is in Europe's interest to do a trade deal. If they don't Euroland will go into recession too.
If the U.K. goes into recession it will be less attractive to immigrants. Which will be beneficial to people who use the over-stretched public services.
U.K. house prices will also fall which will be benefiical to young people who can't afford to move out of their parent's basement. (Unless they lose their jobs because of Brexit...)
Anyway millions who voted Brexit understand the nature of the gamble. Those who voted Remain are more focused on their own house price rather than what is good for the country. Everyone is selfish sometimes so I respect the reasons behind why people voted Remain.
@MossBoss @Wwanderer. Point taken.
I'm not British.
A quick point on the UK trade deficit.
You are right. UK has a big trade deficit with other European Union countries.
Both sides of the channel are interdependent. Reason why the first sure consequence of Brexit will be a serious recession in the UK and a cost in the range of 0.5 points of GDP on the European zone. Why? When you have a deficit, it has to be financed by foreigner investment i.e real estates selling, company acquisitions, debt emission.
Today, foreigner investment is broken. Real estates is expected to plummet. Without any visibility must investors are just waiting.
The British pound sunk by 10% increasing the cost of imports but improving British exporters competitiveness.
Over the next couple of years, financing the deficit won't be easy.
In other words, EC and UK have to settle on a deal, but the pressure will be much more on UK side because of the imbalanced intensity of consequences and the two years time constraint. The deal won't be favorable for UK. It won't be doomsday but there will be a bit of pain in the process. I seriously doubt UK will manage to negotiate the access to the single market without accepting the freedom of movement.
This is only the economical side of the issue.
Politically, the dismantlement of Great Britain is really at stake. France and Spain refused to start the talks on EC membership with Scotland... as long as they are a part of UK. If Scotland becomes independent, EC membership will just be a formality. Even Spain (with its concern on Catalonia), won't be in a position to refuse the call of Scottish people to integrate the community.
Last but not least, there is some strong inconsistency on the position of UK regarding EC integration.
UK pushed to integrate new nations within the EC (Romania, Bulgaria) in 2007 despite the concerns of France and Germany. Until recently it was the first supporter of the Turkey adhesion (whose borders where crossed freely by jihadists over the last two years).
Now, the same U.K. wants to act against freedom of movement, feeling uncomfortable at the idea to have gypsies settling in the country.
Once again, I'm not British then I cannot judge the feeling of belonging to an insular nation. I would just emphasize that refusing to be a part of European integration comes at a high price economically and in term of political influence. I'm not sure that people who voted Leave realized it.
