It's the relative higher standard of living compared to poorer countries, and language. If someone can migrate to a country where they can understand people and be understood it's at the top of the list. One reason it doesn't happen the other way round is language again. We have the burden of English being spoken as a second language in many other countries, so there is little incentive to really push language learning in school here. It's foolish, but there is a logic. As the UK becomes poorer compared to the rest of Europe there will be those that will wish they could speak a second language. Not that it will do much good, as post-Brexit unless you are rich or a high performer there is very little chance of landing a job. The British population happily voted away that right.
