Well, I'd like to see all state-funded schools have the same admissions criteria, and I'd like there to be no faith schools. I know I won't get that, though I think it's a pity faith schools weren't nationalised at the same time as the health service.
But the impact on communities - particularly crowded communities where it is difficult to maintain a sense of community - shouldn't be underestimated, and needs to be addressed.
I'm quite attracted by the 'let the faith schools have a percentage of places based on the amount of annual funding they put in.
Yes, I hear the argument that good non-faith schools have people 'buying' their way in by buying homes in guaranteed catchment at an inflated price. Trust me, I get it, I couldn't afford that option.
But neither am I willing to buy my way in by means of hypocritical churchgoing, which is what a lot of people do and is openly tolerated by the church.
I also quite like the entry-by-lottery to oversubscribed schools within a catchment that you see in some parts of the US. Helps with the buying-a-place argument.
