My children were all entitled to free school meals. We lived in a quite a middle class area - and lived in our own (mortgaged) house. My husband - with high professional qualification - was unable to get a job (desk one), as he was in a wheelchair - back in the 70's & 80's no disabled employment law). I have since learned that my eldest daughter, never had any lunch when she was in secondary school as she refused to go through the humiliation of being separated out to receive these.
we did not smoke, but did have a colour tv, our own very nice, new build house AND even managed to run a car (with disabled Dad and six children that was imperative.
I suppose people like Gwyneth would dismiss us as being feckless parents. I would repeat what is said in To Kill a Mockingbird about not making comments until you have 'walked in their shoes'.
Yes, we had six children, (last one adopted), like the house, came before my hubbie became disabled. I can remember the frightening times of trying to make a small amount of food stretch a very long way, or even deciding whether milk or bread should be purchased on some days,
Due to their experiences all my children (and they all went through full education including Uni) are now employed in what would be considered Service work - Education, NHS, etc). All have good careers, although in this sort of work none of them will make a fortune - but all remain caring, empathetic people and help out with such things as food banks, etc. etc.
I also know that many poorer people today do not even have cooking facilities, even those that do, may not be able to afford to use them at times. so provision of food items that require cooking are not really very helpful
