First, the figure surprises me too but at the same time, i cannot imagine so many people would maliciously lie just to skew results. The poll is anonymous so it's not like anyone's ego is getting stroked.
Also, $41/hr is not necessarily the same as 85k a year. You already see evidence of this from the little 17 year old kids that run their own "PC Business" aka installing a printer for the neighborhood grandma. They claim they make $41/hr. Sure that might be true. But they certainly don't make $85k a year.
