Yes, completely agree twinsetandpearls and it was exactly what JP was complaining about. Yes, you can better yourself, yes, he did, but he is still regarded as 'a bit of an oik' by the people he mixes with because he hasn't changed himself, his accent for instance (unlike Pauline) immediately sets him apart.
I do agree, in part, he is his own worst enemy and a lot of stereotypes were trashed for his benefit on the programme. But the main point still remains. You can make lots of money, you can work your way up, but unfortunately 'money doesn't buy class', rightly or wrongly and that was the point he was making. Quite well I thought, especially as the slightly sneering commentary pointed out about his nice house etc. I'd just give up if I were him!
He seems quite a pleasant chap to me and hopefully his stereotypical image might have had a bit of a makeover after this prog. Obviously the press have got it in for him big time.
