I still think that better management in households on Benefits would improve the children's health and well-being.
We visit an Asda about every ten days, to get certain items not sold in our favourite Tesco. This Asda is right in the middle of a social housing area which has many problems with crime, drugs, fighting between tenants and so on. Many of the mums are single and on Benefits. (I know this because the school where I worked used to liaise with their school) I don't judge, I merely describe.

I watched the customers yesterday with interest. Their trolleys were crammed with packs of 24 sugary doughnuts, frozen ready-meals, gigantic pizzas, large tubs of ice-cream, several loaves of white sliced bread, and the inevitable huge plastic bag of frozen chips. The women always stop outside the main door to have a smoke while their children run all over the car park narrowly missing being run over. Nearly every person (male and female) was literally covered in tattoos and piercings, and everyone's hair was dyed in startling colours. Many, adults and children alike, were very obese.

Now I merely wonder - if they stopped smoking and buying cigarettes, paying large sums of money for tattoos and hair-colouring products, and spent the same amount at the checkout but for more nourishing items such as vegetables, inexpensive meat cuts, fruit and eggs, would their health be better, and would their children be better fed?
I honestly believe that these women (and men) have never been shown how to live on their income. They mostly don't work, so they do have the time and energy to cook, (eg home-made meat pies, casseroles, vegetable soup and so on) They need guidance and support with budgeting and correct diet.
I also have to add that in this area there are jobs to be had. It isn't suffering from unemployment. In fact, they're crying out for carers, checkout assistants, cleaners, waiting staff and many other non-skilled workers.
