Chris, Who are these professionals you wish for ? Do they exist ? The grass isn't always greener on the other side, the same accusations are made at UK short circuits.
I do agree with your comments about the wasted money on 'socialising'. I have always believed that too much money was spent on this and the importation of officials who are paid and receive free accommodation.
Another issue of money not going to the riders is the payments made to Flag Marshalls (white coats) but not to trackside Marshalls (orange tabards). I do not believe that either should be paid as each is as important as the other and both positions should be voluntary.
