Teachers vs Babysitters

Do we pay our teachers enough? I did a simple calculation the other day thinking about what it would cost me to have one of my kids watched by a babysitter for the same amount of time an average student is in school. Here is my math:

6 Hours X 180 Days X $5/hour = $5,400

Now that doesn't seem like a lot until you put 20 kids in a class room.

$5400 X 20 = $108,000

I'm not saying we should pay teachers $108,000, but it sure makes you think about what we are paying them per hour per student.
