I guess that distinction in poor matters some to me, because when I read your original comment (budgeting to avoid staying poor) the first thing that came to mind was someone I know who often says things like poor people should just work harder and variations of that. And then I'm thinking like food deserts or people dealing with more pressing issues where there's probably a general inability to do any long term planning. And in that context it comes across as out of touch or like a naive solution to a complex problem, but then I guess you also have broke college students and others who could certainly heed this advice, not just necessarily low income people.

Even if you live in a food desert you could make cheap unhealthy food at home and it will always be cheaper than McDonalds and with even just a little bit of creativity it will be much healthier too
