We can afford to, but are choosing not to.
We moved to an affluent area with fantastic Primary schools and Grammar schools.
Both DH and I went to Grammar schools, so we assume our children will too. I have tutored children for the 11+, so would do the same for my own.
Pre-DC I was an English Teacher and worked in both Grammar schools and Comprehensives. I also have experience in Primary school, as an LSA and as a private tutor; therefore I feel that I am able to provide a lot of input myself.
We feel that our money will be better spent supplementing their education with extra curricular activities and lots of travel.
