There are numerous things to raise here.
Having a famous name or a difference of some kind like Hamilton or being female is a marketing teams dream. Think of a Pic, Vergne, Kvyat or Buemi. Talented, deserving of being there, but instantly forgettable in marketing terms, they offer nothing new for sponsors.
A famous name or a black kid or a woman does, harsh as it may sound, new markets, different markets. Look at Ericsson, his backers are so keen they basically bought the team he was in!! He is nothing special, but you can't fault the enthusiasm of his backers. That is taking driver backing to a whole new level.
So a new Alesi kid or Schumacher will get there because of marketing first, as well as talent. Sad. And too much pressure on them.
Regarding gamers, I think Mardenbrough has set it all back a bit. He was supposed to be a shining light and then they got hugely negative PR with his crash at the Nordschleife. That is NOT what companies like Nissan, Sony or the like want. None of the other people who have won have done anything remotely worthwhile other than the first lad who won, so I think that gimmick has been proven to be a failure in terms of producing racing drivers.
I have said all along, if I had that much money spent on me in terms of training and gifted drives, I along with millions of others could do as well as they did. It proved nothing really, but was a great marketing gimmick.
Nothing whatsoever is being done by our insipid MSA to push kids into having a go, I would love to know how much money they have, how much they could throw at a total novice race recruitment drive. But sadly they do absolutely nothing and to me are a total embarrassment when you compare them to FFSA or ADAC for instance.
