I do object to the sloppy and muddled thinking though.
If you are going to opt for a state education (and I didn't) then the choices boil down to grammar school, faith school or normal comprehensive. He discounted the faith school, rightly, as he wasn't a practising whatever-faith. He was silent on the grammar school issue, apart from saying he didn't particularly not believe in them, so we have to draw our own conclusions. And that left him the choice of his local ordinary comprehensive or moving to another area and going to that comprehensive school.
Which comes back to UQD's chorus of there really isn't that much choice.
I've heard and met lots of people moving catchment areas, but only ever to be in the catchment area for a grammar school. Are there a lot of people avidly chasing that 2% A-C grade differential? How will they know that their 'superior' choice will be superior in 5 years' time?
It's utterly sloppy thinking.
