You're not plugged into the community because you're not even taking part in it.
The local school is the primary focus for the community. If you don't use it, you are not taking part.
It can't be that hard to understand.
You can argue about loony left-wing policies, but those comprehensives wouldn't be failing if everyone was made to use them. At the moment we have many of the high-achieveing, supported middle class children creamed off by private schools, which doesn't leave much hope for the most vulnerable kids, many of whose parents/carers couldn't care less what sort of education they have - of course the schools dominated by those kids are going to fail.
Furthermore, at least the "loony left" is trying to make life better for those at the bottom. There is really no sign that the Tories feel the privileged in this country should have any responsibility whatsoever for the poorest and weakest members of our society.
That is what troubles me about Cameron. I do not trust that he has any particular empathy for people on the poverty line. And, yes, I do think his Etonian background contributes to that.
To qualify all this, I was privately educated at a very expensive girls' school in London and I have die-hard Tory-voting parents who live in an absurdly large house, own two other properties, and do not see why they should have to help anyone else ever. So I have not "inherited" any left-wing tendencies from anyone. I believe strongly in social cohesion, but I do not think the Tories could give a damn about it.
