If you assume 180 days of school at 8 hour days = 1440 hrs, plus 200 hrs of various other time spent outside of school hours or active school days, you get to 1640 hours a year. 60k/1640 = $36/hr. Not bad. Not great.
When you factor in vacations, holidays, etc. in an office workers' work year, the 2080 hours that gets thrown around...companies will generally find that their employees are working ~85% of the work year. This ends up being 1768 hours a year, without considering any OT hours. The workload difference is not as big as you make it out to be.
