According to Joan Bakewell the reason that "toffs" are not unfashionable anymore is because we all like to wear lots of bling as status symbols. Ergo, being rich is acceptable. However, read on in her column which is about nothing more than envy politics.
She argues that being a "toff" (a perjorative term of course) does not exclude you from being the right person to carry out a job. Nor does going to Eton. However, if everyone around you went to Eton then it is bad. She then says in closing,
David Cameron is rightly credited with charm and understanding. But he comes from a tiny elite. As I hope Crewe will tell him, it's time he looked further afield.Yes, he does come from a small circle, but one look at the guys diary and travelling around the country suggests that he already is looking much further afield.
What school someone goes to is utterly meaingless. I bet Bakewell would not deploy the same logic if there was a small circle of influential politicians that all went to the same comprehensive.
