Yes. And if parents choose to feed their kids processed junk food instead of milk and eggs, what do you?
I was lactose intolerant from an early age, and refused to drink milk. When I went to school my mother made lunch for me. No processed junk food, but her sandwich-making skills were terrible and I hated
Marmite. I trying giving it away, and when that didn't work I threw it in the bin. I got into trouble for that, but they couldn't
make me eat lunch so eventually they gave up.
It could be argued that not supplying a lunch attractive enough for me to eat may have reduced my potential intelligence. OTOH the effects of tetraethyl lead on growing brains are well known, so having to go to a school in the city
definitely did.
BTW 'processed' food isn't necessarily bad food. I challenge your implication that poor people only feed their kids 'junk' food, but even if they did so what? The point is what the kids eat when at school, not at home. If they aren't getting anything for
whatever reason, then that's an opportunity to make sure that at least one meal a day is healthy.
I get where you are coming from though. I mean, if parents can't fed their kids properly then why should taxpayers foot the bill? A very shortsighted view. Our economy is critically dependent on having an effective workforce. As our technology gets more sophisticated we need smarter people to maintain it. That also means 'dumb' people can't do those jobs, and more will turn to crime. But of course you don't care about that. You only care about having more money for yourself. Well not me. I would gladly pay a little bit more tax to have a healthier, happier population of smarter people who will make the world a better place for
everyone - including me.
