Saski - apart from Bonsoir, I don't believe anyone said the government DID have a meaningful role in what we eat, did they? I said it gets involved in food policy at the moment, not food micro-management, and it does, at national, European and International level, and a lot of taxpayers' money is spent on this. It does get involved, as closely as it thinks it can possibly get away with, in order to protect public health (and this is only really so that it can increase its chances of having people healthy enough to be able to work and thus pay tax...) - our chocolate bars do not generally contain dangerous levels of toxic pesticides, for example, and if not eaten to excess will not do us any harm whatsoever. Along with considering increasing tax on anything with sugar in, precisely with the hope of controlling what we eat, government is even considering fluoridating our water supply, which I think would be considerably harder to avoid even than state education.
Where education has a special place, of course, is that it is seen as a way of gaining some control over the way we think and behave, and thus increasing control over all the things others seem to be claiming the government doesn't get involved in... like what we eat, whether we exercise, how hard we work, whether we pay tax, whether we are good citizens of the Big Society, etc, etc. Trying to crush the teaching unions could be seen as just another way of ensuring the state can get more control over our schools and our lives, so that we can all be kept running around in our little hamster wheels, unable to get off, but too blinkered to see or understand what we are really doing, anyway.
Basically, the state is very interested in having control over all areas of our lives and if it can't do it through schools, it will still find other ways.
Interestingly, the more the government claims it is very hands-off and small-stateish, and pro-private enterprise, the more I feel exploited and controlled by said government - they even want to mine all our private medical data for information and profit.
We have never, really, been so controlled as we are, now. And it's not just the state wanting to control us, but multinational corporations. It's all a big battle to control us, so that we can be mined for profit.
Big Brother is watching you... even if you are at Eton.
