If you look at the charter of the religous orders that run a lot of the top catholic schools they are on about providing education for the poor / people who would not otherwise receive it.

Good on you mattsta - i won't be sending my kids to a private school either - i'd rather send my kids to a state school and buy them the rescources they want!! - That's cos state schools provide things that money can't buy!!!
