To Becca: I agree. Decide what is important in your life and prioritize your budget around that. We send our kids to private school. We don't go to Disney, and my car is 12 years old.
To Marie: "Many Christians are no longer Christians" I understand what you are saying, but parents have to do their homework. I wouldn't blindly send my children to a private school without understanding what they are teaching. Assuming you understand, there are outstanding school choices out there for the willing.
