I send my child to a faith school and it certainly isn't funded in the way applecakes school is. We are NEVER asked for contributions - although there is a PTA for fundraising. The church owns the building though, and the 10% is taken from collections in mass.
It's usual to be church-going, yes. But there is a little boy who's muslim going too.
We are an inner London school - and have plenty of Sri Lankan, African, South American, West Indian, Polish kids there.
Lots of nice families - but by this I absolutely don't mean all rich - ie some very poor.
Think it's quite amusing the way people get so pissed off about the whole thing. In the 70's/ 80's no-one wanted us 'immigrants' - mostly Irish - who went to RC schools. Then, despite our parents being poor, we actually did quite well for ourselves, and people get resentful.
