I went to an English so called “public school” in the 60’s.
The behavior of first Blair and now Cameron comes as no surprise to me. At the risk of seeming judgemental, I knew lots of these kids, and believe me, they all run to type. (Not to say that all the kids at that school were like that, indeed no.)
These kids were (and remain) entitled, utterly self-confident, with a belief in their right and obligation to reshape the world. This came from class, from socialization, and from arrogance. (This is not the arrogance that defends against uncertainty which many of us might be accused of being guilty of, but rather the real, necessarily un-examined, thing.)
These kids really believed (and believe today) that their privileged education was some kind of earned reward. To the extent that it might really be a reward to their ancestors, that was just as, perhaps even more, fine.
Moreover, that education prepared them to rule the world, again not so much as a matter of technique, but of utter self-confidence.
John LeCare, in Tinker Tailor Soldier Spy, perhaps got it best when he had Connie Sachs, the forced-out British intelligence research head (quote reconstructed from memory) say, with more sympathy than I can muster, even now:
“Poor dears, born to rule the waves, and now with a voice that hardly caries across the water.”
Its no surprise that being Bush’s poodle might have some appeal. Nor that one might grossly misjudge ones ability to manage a referendum process.
