According to Cameron, the UK has an immigration problem. He aims to fix this problem by making immigration much more difficult. But more difficult for whom? Tomorrow, the entire population of Greece could move to the UK.  There would be no legal barrier to prevent this, and in all honesty, I'm not sure why that hasn't already happened. However, if an engineer from . . . say . . . the US (or any other non-EU country) wants to move to the UK, this is nearly impossible.  It is a ridiculous situation.  There cannot be an economic union without a policy union.  And when, historically speaking, has Europe ever had either.  I'm going to make some pasta and get some sleep.
