It's because it does matter to the outcome, if you consider the outcome to be more than just GPA. GPA is not the best indicator of whether it's a worthwhile investment. The selection of a private school takes in to account additional factors like the environment you learn in, the connections you make, the college prospects you get and also the mere existence of religion.

Could you expand on the "mere existence of religion?"

Private schools are often affiliated with religious groups (Catholic, Jewish, etc.) For many people who choose private education, the existence of religion classes in school is a large factor.

In the case of this particular study, it seemed that the quality of the school as a factor was overshadowed by the desire to learn, as shown by the attempt to get into a better school. This does not mean that the quality of the school does not matter, simply that desire to learn matters much more.

because a private school would not have confined my friend's child to special education because she spoke Spanish in class one day to a friend.

Perhaps rich people are getting the result they believe they are supposed to receive? As in, their behavior is modified in minor ways they do not perceive but all towards the goal of increasing the success of the children they enroll?

It really comes down to parents. Children are not autonomous for the early formative years and how the parents treat them, from setting their morals and encouraging good behavior sets the course for most of their life barring abrupt unforeseen external forces.

I have only one issue with private schools, I do not believe any politician should be allowed to send their children to one.

That is odd.. so politicians should have less freedoms than the citizens they serve? Good luck finding someone to elect. It is bad enough political organizations go dredging through their personal lives. It amazes me people are still willing to serve in public office.

I will give you the reason, I tire of them incessantly telling other people public schools are well and fine for other people's children but they find all sorts of reasons to prevent their children from attending.

So, they need to sleep in the bed they make. If they don't offer parents the choice of what schools to send their kids too on the basis that their schools are perfectly fine then why don't they stand behind their words and send their own kids there.

Yes I support vouchers, I think schools should have to compete for the money. The money needs to follow the student, not the school. In the nearly forty years we have had a Department of Education the only thing that has gone up is the cost per pupil, scores certainly have not.

Because going to a private school gives your children the opportunity to network with the children of other wealthy people.
