They're good salaries, but they're middle-of-the-road for a professional, white-collar job. As far as mid-career salaries by profession go, software engineering at ~$100k isn't even midway between history major (~$75k) and petroleum engineer (~$160k).
Plus, everyone on all sides could be accused of whining, because the entire technology industry is well off compared to most people. When a VC complains about terms on a deal, you could ask, why are they whining when they're already well off?
