It all depends where you live. In my neighborhood (Portland Suburbs), the average house price is $400,000 to $500,000. Our public school is about the same as a private school.
Riverdale School District, in Southwest Portland is a totally exclusive school, of course the houses there are very pricy, if a house sells for under a million they will advertise it as Riverdale School District in the paper.
One thing is true though, there is no way in hell I'd ever send my kids to Portland Public Schools.
Hey, that's not fair to the poor kids. You must be enjoined to send some( a lot) of your money to the Portland schools to make it fair. That's what the state of Washington does.
