> The luxury isn't cooking. The luxury is being able to have a large room full of machinery dedicated to preparing meals for, on average, 2.5 people. These days, average people can barely afford living spaces as-is. That room adds to the cost substantially and is not likely to be recouped against eating out, unless eating out means eating at places that are selling entertainment alongside food.

So, my kitchen has a range, sink, dishwasher, and full-size refrigerator. It is small but it is a full kitchen. It is the smallest "room" in my apartment; I probably pay a few hundred dollars a month for it. The cost difference between cooking at home and eating out makes up for that in a couple of weeks for me.

Kitchens aren't that expensive.
