The new visa system for immigrants is very scary indeed.
If you have an MBA or a £150,000 salary, you're in at Tier 1: immediate visa. If you have a PhD and an academic salary, you're Tier 2: limit of 20,000 people across all industry.
So to sum up: if you're one of the thrusting business monkeys with an expensive qualification in the kind of economics which bankrupted the entire country, come on in. George Bush has an MBA.
On the other hand, if you're a young academic with a PhD, which in itself announces that you've made a clear contribution to your field (and most brilliant books and amazing discoveries are made early in a researcher's career), you can sod off, however many things you might invent and students you might inspire.
The Hegemon is suffering already from the reduction in visa sponsorships it's allowed.
Clearly, Britain's on the right track.
