Hate to do this this, PDQ, because I think you've got a good point there, but the cost of private school is way more than you've got listed--this article, quotes statistics from the National Association of Independent Schools, who say the average is $22,000 per year.
Private School Financial Aid Religious schools, or, as they like to call them, Parochial Schools, are much less--depending on where you are,Catholic schools can run around $5k for elementary and $10k for secondary. Quaker Schools, which have about the best reputation, run considerably more(and tend to have a very low percentage of Quakers).

The money spent on schools, and the money spent on education are not the same thing. The largest expense in our school district is transportation. Teacher'pension funds are a huge expense(not necessarily against this, just pointing it out). The cost of actual
instruction is pretty close to that of building and property maintenance.

I think education is really important, but I also think that we need to get some of those Walmart people involved to help get the costs down where we can afford them.
