I feel like the comments are misunderstanding what's happening. Historically luxury food has been nice ingredients but now that's everywhere, and what consumers really want is delivered food. They want the thing they want, only made 6 miles away, hand delivered to them and still warm. This is a luxury good, and like many luxury goods may now be financed.
Cheap food is not going away; my lunch every day costs ~55 cents to make. In this context of luxury goods, the article makes more sense and isn't some dystopian nightmare like people are implying, it's just another luxury good you may buy.
