It's not mythical, it's very real. Look at the constitution and educational credentials of UK cabinet ministers and Parliament. It's often Eton > Oxford U. In order of prestige, it's undeniably Oxford, Cambridge, and Imperial in that order (and St Andrews if you allow for Scotland). The reason why name-dropping Oxford in that cringetastic manner is done is because people respond to branding, just like Americans do with Ivy League schools such as Harvard and Princeton.

Yes, and as another poster stated above, it quite clearly should NOT be that way.
Just going to Eton and/or Oxford does not automatically make you a highly intelligent and highly capable individual ... the present UK cabinet is an example of how that route manages just as easily to push out a bunch of incompetent twats.
Nowhere was the claim made that an Oxford degree makes you intelligent or competent. And in this thread, we're not dealing with the way things should be, however you or I see things. It's simply acknowledging the way things are.
