Oxbridge References

Reading a debate on education in the Guardian recently, I noticed that once again Oxbridge seemed to get disproportionate attention.  This always annoys me.  Debates around higher education in this country always seem to degenerate into references to Oxford and Cambridge, as if they were the only universities in the UK.  Obsessing over two universities distorts the whole discussion.  Perhaps there should be an equivalent to Godwin's Law to prevent this.
