Mike Moritz said something similar at a forum with Guy Kawasaki once. His take was a little different. Basically big success are common with the under 30 crowd because they can take more risks, swing for the fences, not worry about feeding mouths, etc. He put a finer point on it quoting Evelyn Waugh who said something to the effect of "the greatest impediment to creativity is the sight of a pram (baby carriage) in the hallway" I'm sure there is some age bias, but also a lot of it has to do with risk profile.
