Also, the time cost of preparation.

I don't think there's a common understanding of how much time working class people have to spend on work. It's frequently on the order of 50-60 hours across more than one job, plus the attendant transit and pre-work chores. Your job doesn't provide you with cheap, healthy food on-site. You frequently can't eat on the way to or from work, per transit rules or enhanced police presence on your route. Lunch breaks are a strict 30 minutes, and being late can get you fired (hope whatever you're eating doesn't have too much fiber). You may have to go out of your way to shop, if you live in a food desert, and apartment fridges preclude buying in bulk. Oh, and for a racial angle, produce in cities (and, not uncommonly, in majority-minority suburbs) costs more than in white suburbs and rural areas.

We have so many UX experts on here, is it really that difficult to think of this problem as an experiential narrative instead of an engineering problem that can be solved by tweaking a few variables?
