It's dangerous to extrapolate from there to "nobody makes that much". It's only a short leap to "I'll never make that much" and eventually, "$70k/year isn't so bad".
There are in fact lots of developers doing nothing but development making well north of $200k. That's less than a $100/hour bill rate, which is not at all uncommon as a contractor. If that's something you want, know that it absolutely is attainable.
I think you'll find that, in all walks of life, people who make lots of money tend not to post on internet message boards (or salary surveys) about how they make lots of money. Definitely don't take the lack of people spouting off here about their 1%'er incomes as a sign that those people don't exist (or aren't, in fact, here reading this thread).
