The state of the freelance job market - Exquisitejobs survey results

Assuming a 2000 hours/year (50 weeks, 40 hours/week), that's only 126k (gross, probably 50% of that net after insurance, healthcare, expenses, etc.), and I highly doubt most people working freelance work 2000 hours in a year as a whole lot of the job is unpaid hustle to get the next job.
Most smart tech people are worth, at minimum, $100/hr in a consulting/freelancing capacity.
Are you trolling us? The survey questions only had spots for web dev, design, ios and android. What about working on metrics, databases, desktop software, games, systems programming or just general server side code?
