Three days a week is sufficient

Mish talking about the four day school week in Illinois:

Not one person mentioned the real [budget] problem: bloated administration costs, union salaries and union benefits for teachers, bus drivers, and janitors. Instead they are looking at saving heat and electricity one day a week. Good grief.

My take:

With technology and personal study, students are better off with a three day week, on an irregular schedule to meet in a seminar for each class once a week. We have a budget problem because advancing technology has discounted the babysitting function that teachers perform.

Using trained teachers to perform babysitting for the parentless kids is a waste.
