The UK's current gov is firmly wedded to a delusional image of itself as a major imperial power of vast wealth and influence. Such is its majesty it is for ever in danger of being infiltrated and undermined by unpleasantly independent Europeans, who for some reason refuse to see the UK as the most important country in Europe. And also by nasty brown and black people from who knows where?

All policy is designed to reassure itself of that view. Not to solve practical problems.

In the real world the number of top graduates who will want to stay on with a two year work visa - and no guaranteed extension - is somewhere very close to zero.

There's no conception that other countries may have a more appealing work culture and a more open and successful academic culture.

As it happens, the university sector in the UK is currently closing many departments and firing and re-hiring many of its professors so it can cut their pay. As a result many are on strike and others have left.

Any student who is reasonably bright and considering the UK is going to know this.
