And the EU wins because the best and brightest will want to move to Europe to work after the clocks start to turn back here.
The "best and brightest" always could get a visa to almost any country in the world. Free movement was for those that aren't.
Not being able to use the UK to supply low and medium skilled jobs, education, heathcare, welfare and other services to EEA citizens and their Family Members, is not a win for EEA countries that rely on the UK to provide this as they always have high unemployment, ie France, Italy, Spain and now the newer EU members from eastern europe, ie Poland , Romania etc.
The last UK census showed that the Polish and French were in the top 10 list of immgirant numbers. When only those on UK visas could live in the UK, these countries didn't feature in the top 10 ten list of immigrants. The UK stats only record immigrants by their citizenship and not whether they entered the UK on a UK visa or via EU laws/Eurpoean Court rulings.
This is why France (the 3rd biggest giver to the EU budget last year) broke EU ranks straight after the Leave vote and said they want to trade with the UK as they also export a lot to the UK too.
Whereas Poland (the biggest taker of the EU budget last year to the tune of 10 billion) tried a dfifferent tack, or rather their ex PM Tusk did via threats. Acccording to the Polish press, he was in a lot of trouble in his home country as they blamed him for Brexit. Poland also rely on the UK (the second biggest payer into the EU budget in 2015 and the biggest payer per capita - and the biggest contributer for loans to EEA countires) for protection too from other EU countries for others things, such as protection for their own currency.
But then we also have the bizarre letter to the EU from Poland and 3 other Eastern European countries, saying that they don't want migants in their county - but they want their citizens to be migrants in other EEA countries
Although we already have another EEA country capping numbers of those wanting to use free movement to their country.
Then look at how quickly Germany and France have turned on Ireland after the UK's Leave vote, to end Ireleand's low rate of corporatiuon tax to get jobs to Ireland. Ireland had already published that they thought that might happen if the UK was no longer there to protect them. Ireland campaigned so hard with the EU to change to stop the UK leaving and then asked all the Irish living in the UK to vote to stay.
Free movement? With or without the UK, I can't see it staying the same as it is now.
