In poor areas, there are few markets or local shops which sell fresh fruit and veg [...]
I don't live in a rich area (moderate, at best) and live close to some very poor areas. The market I refer to isn't in a rich area either.
[Ms Marshall] does paint the broad brushstrokes - debt and inflation.
That's the problem: broad brushstrokes can easily be filled in with assumptions.
My neighbour must have begged over 30 quid off me, delivered in £1-2 installments. Every time, it was to feed her children, and would be paid back. I knew both parts were, in all likelihood, lies, but it didn't seem much, and I felt sympathetic. When I finally refused to lend more until the debt was paid off (it never was, of course) I was clear that she was welcome to have food for the children. The frequent visits ended. All she asked for over the next year and a half was an onion! Alcopop bottles and fast-food cartons continued to pile up.
Lack of money clearly wasn't her major problem; instead it was her inability to manage money, and the rest of her chaotic life. However much cash was thrown at her, I doubt it would have helped.
Now, if her situation is anything like common, it could lie behind Ms Marshall's claim that parents can't afford to feed their children. Or maybe it doesn't. All I know is that I'd need to see details from Ms Marshall before I accepted her claims. But to investigate, Ms Marshall would have to be wise to the messier parts of human nature. Again, perhaps she is, but I've seen many people writing in the
Guardian who aren't.
