The point that Marty Smith was making is similar to what Bob Hannah has been saying... so many well-off posers have turned the sport into a fashion show.
The ONLY thing that counts is heart. Look at some of the best racers in recent history, like RC and James Stewart, these guys came from working class families. With the rules set to four-stroke friendly, meaning really expensive, families like the Carmichael's and Stewart's will be pushed out of racing long before they can reach their potential. This will be the largest destructive effect of the four-stroke rule.
The true determining factor must be about the person who straps on the helmet, not how much money they can put into racing...
End of rant...
