It's a nice number, especially this year!
I know reasonably well maybe a dozen of so who fall into the category and a couple who I think qualify as high net worth individuals which is >£25m I think these days before HMRC take a bit of an interest in you?? One is definitely not playing with a full deck and I would say is amoral rather than immoral, another is just a nutter whose made money in security but the others are mostly in that third category. A few of them are state school and are down to earth types but even then come from a reasonably comfortable albeit not posh background, I can think of one from a similar background to halfmist. I once had a boss who was very much in the self-made man category, very bright and sociable and looked like he had everything going for him including family and big network of friends, he was someone who lots of us took as a bit of a mentor but one day out of the blue, he booked into a hotel room and killed himself and it seemed like the pursuit of ever greater wealth might have played a part. A sad sad saluatory situation.
It's a really interesting subject, about 18 months ago I fell into working with some academics one of whom has a specialism in understanding how social capital impacts life chances, some stuff is obvious other bits less so. There's all sorts of factors but education (in the broadest sense) is a key thing which can make a difference, which is why I would love to see it stop being used as a political football. The number and type of Secretaries of State we've got through over the years is farcical.
