CMU is the EU trying to take control of the financial industry via their usual trick of "harmonizing" rules rather than allowing differentiation with mutual recognition. It doesn't address the problems actual voters had around unlimited immigration. That is taboo for the EU.
Free movement enhances trade. The US doesn't restrict people from moving between states. The UK wouldn't accept Scotland trying to reduce people from other parts of the UK from working or living there.
> a negative to basically everyone
That's a politicised absolute which is clearly false. I think your political biases are colouring this.
I go back to my previous example. The UK doesn't try to impose government control on movement between its constituent countries, and the US doesn't limit movement between states. Freedom of movement improves economic outlook.
All EU countries are reasonably affluent by global standards. Some countries are richer than others, but it doesn't make economic sense to move from a country where you have a job to claim benefits in another one.
EU countries aren't obliged to pay benefits to people who have never worked in the country, so your idea that "governments will pay for benefits" is a very simplified view.
Absolutely agree it is a good thing. Probably not everyone sees it that way though. As for the British people choosing to wind the empire down, I must have missed that referendum.
> No, that's a common claim but not really true. The UK had very little influence inside the EU and the EU rules were almost always made to satisfy the needs of either the EU institutions themselves, or the domestic economies of France and Germany.
All I can say is that as a lawyer in the EU (who works closely with the UK) that is not my perception or experience. EU financial regulation heavily bears a British stamp, and the single market was immensely beneficial for London. One of the main EU initiatives that was in full swing just as Brexit happened was the Capital Markets Union which was absolutely a UK-led initiative, headed by UK Commissioner Jonathan Hill. Since Brexit happened and Hill resigned, that initiative has trundled on, but has completely lost momentum and not really delivered what it was supposed to.
> Scotland would have to apply to join as a regular country and its finances are in no state that would allow that.
This seems as over-confident a prediction as the predictions that the UK would never vote to leave. The EU took in Romania, Hungary and Bulgaria for political reasons, it is not that much of a stretch to say it could take in Scotland.
