But hey, happy fishes and being able to flaunt that stylish passport on the massive customs queue
Maybe I should get myself a job in the continent and move there...
The UKs trade swagger is demonstrably worse without free access to the single market. Numerous academic studies have shown that long-term the UK will be worse off.
Trade is the big one.
I was a poor European who moved to the UK and I've seen first hand the problems that immigration of poor people can cause on crime (from drunks to petty theft to stabbing) and how much the locals dislike it.
I've seen the same happening in Italy and the situation nowadays is so bad I would be genuinely scared to live next to the train station in any major city in Italy.
I think a model based on skills is the best approach: if you want to move in you should be able to prove you're skilled and that we need you. Once you pass the checkboxes the process should also be much smoother than what it is right now, the typical bureaucratic nightmare.
There are a lot of ways Brexit could have been implemented. One extreme would be to make it so the UK has no special arrangements with the EU. It would be just another non-EU country, like say Mexico or Japan, that trades with the EU. Agreements and treaties would arise eventually to deal with issues as needed.
The opposite way would be to make it more like say Norway. Norway is not a member of the EU but is part of the Schengen area along with many EU countries greatly easing travel. It's part of the European Economic Area, easing trade.
Are politics in the UK stable enough that at the time of the vote one could predict which kind of Brexit would be implemented? I don't think anyone seriously thought that Brexit would be fast, so implementation would be years after the referendum.
