I lived in the now EU for over a decade before the EU was as it is now, and that figure shows that you can move abroad if you really want to.
Rules of life change and they change constantly, but if you want it you can do it. If remain would have done a better job of convincing people then we wouldn't be in this mess in the first place.
How many foreigners from outside the EU live in the EU? The recent figure is 24 million, that's 24 million people who don't reside in the EU are living there now.
My argument isn't in bad faith it's just dispelling the many myths generated by people who didn't like the decision.
