I agree David and John. I have no intention of returning, I would be a minority in my family proposing such a move if I wanted. I am not so narrow sighted I do not see and accept the fact of a sinking ship. Pro-Brexit people are creating scenarios when the future is unforeseeable. To assume that there would be 'no change' of status in Europe and such speculations are folly. The UK is likely to build up resentment with its attitude and create barriers between themselves and the rest of the EU, the cause and effect are predictable but the outcome is not. I would rather take my chances as a British citizen in Europe rather than anything else. So, personally I do not want a crystal ball anyway, the path I have chosen is my own - or at least the one I share with my family.
The cuckoo in the nest there is the economic migrant line. Firstly, the present wave of migrants are mainly refugees. The EU migrants to the UK will be entitled to go there anyway, as long as the UK remains part of the EEA. Leave that and then the UK is truly alone. Assuming trade with China, India and so on is going to save the UK is naive. Even the newly signed agreement with China is petty cash in real terms. Apart from that, the small print is more about Chinese investment in the UK. On form, that means more businesses will be owned in part or whole by Chinese banks, production begin in China, parts assembled in the UK and distribution begin there. However, out of Europe China will go for direct sales because with UK subject to new ex-EU tariffs... Finance is not welded to the City, get that wrong and it is gone. There are other places ready to assume that mantle. However, the misery of several million people forced by circumstances to return to the UK is a factor nobody wishes to address. There will be pensioners who will lose homes throughout Europe only to return to a country where they cannot afford to buy and limited funds to live independently, there will be many children who have little in common with English language and culture who will need specialised educational support. There will be prime aged working people who will be job seekers. The list is long and unrelentingly full of negatives. But oh no, the Brexiters cannot and will not see the downsides because they will have their freedom to sink in their own misery. I have noticed that several of my cousins who were anti-Indy in Scotland whose livelihoods depend on EU membership have said that they will vote for independence next time round. No, not would but will vote for it because they are taking it for granted that Brexit will raise the immediate demand for a new referendum. So, Brexiters are not mentioning what they must know, that their union will be facing a crisis from which there may be no recovery.
So Brian, you are welcome to your island life, I am far too sceptical to share any positive thoughts many doom sayers like yourself are predicting, perhaps because I am far too much an economists beneath all else and accept that the world has become driven by economics and the socio-political dreams of people like myself come lower in the pecking order now. The large corporations who drive the world invest too much time and money into getting an ever closer world to care too much for a nation that suddenly wants to go off in the wilderness of uncertainty.
