Yes and we will.
We're planning to do state primary till 7 or 11 and then move DD to the private sector. There are no private primary options around here, the state primaries are pretty dire and over my dead body will she go to the state secondaries in the area.
To do it we will not be having more children and we will have to make significant sacrifices, but feel it will be worth it for many reasons.
That said, if we had fantastic local state schools and only 3rd tier private schools we would stick with the state sector.
Both DH and I were privately educated and it's absolute tosh that everyone at private school is fabulously wealthy. We have a small 2-bedroom flat with no garden so hardly a mansion (and no it's not the kind of Chelsea 2-bed apartment) and the two other parents I know of in the area who send their children to private school live in very similar accomodation and have no worries about it.
My parents had falling apart cars, the closest we got to an exotic holiday was a day-trip to France. Thank heavens for school-uniform as all our other clothes were hand-me-downs from our older cousins.
In all the years I was there I never went on any skiing trips or anything like that - and I don't remember feeling deprived because of it or even jealous, very few children went on them.
Very few of the kids were from very rich families - I don't remember any remarks about people's backgrounds at all. At least 20% of kids were there on scholarships or bursaries as well. There was a very mixed intake socially.
I do remember feeling very fortunate to have the facilities, teachers and opportunities I was given.
