That's true up to a point. However, even when I worked in an office, I did not go out to lunch or spend any other money on nearby businesses. It forced me to pack a lunch, and that often meant eating something less healthy. Like, instead of walking into my kitchen to make a salad for lunch, I'd instead keep a jar of peanut butter and a loaf of bread in my desk drawer. It did nobody any good for me to be in an office. It hurt me.
