This is where I love this forum. So many interesting different sides of the arguement!!!
From what I remember back in the 80's and 90's, sports prototype cars and the Formula-3000 were the step before F1.
I remember Jean Alesi, hot shot in Formula-3000 with Eddie Jordan as team manager, got the sponsorship to snatch Alboreto's Tyrell seat half way through the season.
That's become rare these days that a youngster with no F1 experience gets a seat in the middle of the season.
At least Alesi had talent as a pay driver then, but I feel his races in Formula-3000, is what had money thrown at him as with many others.
Also what helped Alesi and others back then, was mid season testing, where F1 teams could test a young driver during any point of the season, which was also an audition for sponsorship.
And that's Berger's point. These days there isn't just F-3000 as a bench mark for youngsters, there's like 3 or 4 different classes, very equal to one another and in each country which are also making GP2 struggle as a young division for F1.
So I'm hopeful for a league system, but as pointed out already, seems impossible due to money, so probably one of the other ways to start solving this, is by lifting the season's restriction on testing for youngsters.
I'm certain if a young Sainz Jnr is allowed to go in circles in an old Redbull flat out for a week, he'll get the millage to net good laps to convince sponsors, and maybe that's what back markers need to scrap in those extra Dollars.
Minardi survived like that.
