Welcome, and thanks for your comments! Please feel free to visit often and post your comments.
Since I can't tell if your comments are tongue-in-cheek or literal, I will assume the latter.
The short answer to your question is - YES, you are responsible only for your kids' education, not your neighbors' kids. And neither you (nor anybody else) is directly responsible for the education of teachers. The analogy is that of your neighborhood grocery store - are you 'responsible' for the salaries of the people who produce food, or (for that matter) people who bag your groceries? No, it is factored into the cost of the product.
A for-profit school would write the following profit-and-loss statement:
Revenue (aggregate of tuition collected)
Expenses
- Salaries
+ teachers
+ administrators
+ other staff
- Mortgage/rent (buildings and other property)
- Insurance
- Annual license fees for educational material
- Expenses for extra-curricular programs
- misc
Profit = Revenue - Expenses
Once we get over the concept that 'for-profit' is anathema in the field of education, it is just another important service that we rely upon. In fact, by bringing market factors back into education, we will improve quality AND lower costs. All this w/out relying on extra-ordinary, superhuman qualities that we expect from educators today.
Many people cannot break their image of education being somehow 'different', requiring Govt intervention and superhuman teachers who do the impossible for next-to-nothing. Reverting to the analogy about grocery stores - and indeed the entire chain of for-profit entities that ensure our food supply. The fact that we don't have to worry too much about the quantity and the quality of our food supply is a testament to the efficacy of the free market in the area of food - an indispensable commodity, perhaps even more important to sustain life than education.
BTW, the following link (courtesy of Libertybob) shows the current costs of educating a child in YOUR state. In other posts on this blog, libertybob has shown how pvt education based on similar numbers would work quite well!
