Man blames media for news

I’m not understanding how that article makes the argument for true food insecurity. They state that many people overextend their credit lines for luxury goods they can’t afford, but couldn’t they be using or have used that credit line to buy nonperishable foods they can’t afford?
To be clear, I’m not arguing that there are truly food-insecure people, or advocating using an effing credit card to buy groceries. But just posting that link in response to @snigs comment doesn’t seem salient to the point being debated.
