Yeah, I don't know the prices of delivery vs. rent in places I wouldn't live vs. rent in places I really, really wouldn't live. But just given the costs of driving in the NYC area, from gas to time to tolls, I would bet on the cheap real estate. Like, does FreshDirect have lower operating costs than, I dunno, C Town?
It's usually cited that the biggest time obstacle to people eating fresh food is the cooking, since they probably grocery shop for the junk food already. And yeah, if the problem is that these people don't have time because they work, then deliveries might have to work entirely after-hours, too, which would also increase costs.
Given that the food isn't ready-made, I imagine that choosing what people will have to cook for them might not good over well, but the convenience of automatic subscriptions might be just as useful as it is to rich people.
And in general, I'm wondering how much actually money/stampage this would save low-income households, barring government assistance (which is already present in the form of stamps anyway). Given that the two biggest obstacles to healthy eating are cost of ingredients and hassle of preparation (the latter of which, let's face it, is a big problem for us, not just poor people), this seems like a possible solution to the food desert problem but not the food choice one -- as long as fresh food costs X more stamps, regardless of the availability or delivery mechanism.
All that said, this is a great problem to put minds to. Way better than, say, 3D-scanning rich people's apartments or writing about sports or some shit.
