Nope. No kids yet. But I have gone to both public and private schools and I know many people who have gone to public schools. It is not possible to generalize as to whether all public schools are bad or good. Mine was quite good.
The essential difference is parental/familial influence versus peer/teacher-stranger influence.
The question comes down to what kind of influence the peers and teachers exert. Again, some places the influences are bad, in others they are good.
If and when you are blessed with children, it will rock your world. It did mine. Lots of thing I thought I was sure about before, I had to re-think.
