Let's start with one of the author's arguments: "many teachers provide private tutoring services to students from affluent families at a typical rate of $50-$90 per hour." Inherent in this argument is the complaint that teachers are not spending enough time on their own students when, in reality, they probably spend every moment of their day on the kids in their schools. From my own experience as an educator, my "lunch break" is anything but.

The research stated also mentions the median work week as 36.5 hours. I find this incredibly unrealistic. Assuming I do not work on weekends, my average daily workload is already 10 hours (multiplied by 5, that is 50 hours/week). If I, like so many other teachers, had to take a second job to pay my bills, that number balloons.
As a teacher I am constantly reminded by the adage, "it takes a village to raise a child." If we only would stop blaming each other and start taking responsibility for each other, things would get better. As President Obama said during his State of the Union address, "As long as we are joined in common purpose, as long as we maintain our common resolve, our journey moves forward, and our future is hopeful, and the state of our Union will always be strong."
