No, that makes perfect sense. The ones with the high SO rep are the ones that have the most time on their hands, the others are clocking up paid hours.
Joking aside, I'm genuinely confused as to how you survey that many of the site's users and get no one with rep above 10k. Especially considering that high rep users are much more engaged and invested in the site, and so I would expect a much higher response rate from them.
