I skimmed both of those links, and while they did indeed show that inequality is increasing, they didn't show the same for poverty.

I urge you not to use food insecurity in argument. Even outside food stamps, food is extremely affordable to eat perfectly healthy. If nothing else it's an education issue, not a food issue.

No comment on job security or wealth inequality.

There are other issues other than money with regards to the cost of food. Time is one of them. The poorer I was the less time I had. No the recipes would not have worked. Healthy food also not readily available. It is not typically an education issue. It also can be a form of addiction in a manner. Many people get addicted when they are young to eating a certain type of way. It can become virtually impossible for someone to break that addiction as they get older. They often get addicted as a child. Lack of healthy foods in many places is a real issue. I live and grew up here tight in the US. If there is a solution for this please do share. I have seen this trap of thought before, I was in it for a while.

In Britain, where food is more expensive than in the US, ignorance about how to eat affordably and well is a shocking poverty trap. Anecdotally, a family getting pizza delivered will be spending almost an order of magnitude more than they would need to by cooking a nutritious meal from easily available basic ingredients; that's fine for a treat, but if you are relying on it regularly to put food in your kids' stomachs it quickly becomes ruinous.
