I remember working retail years ago, and having co-workers that would get fast food for lunch. They're spending 3 hours (after-tax) of of their minimum wage pay on lunch. How much sense does that make?
There are poor who are so exhausted and so without capacity to move up that a little enjoyment from fast food is what keeps them going.
And there are also poor who are wasting resources they could be using to move up. Such as young kids with stable homes working retail/hotel/other lower paying jobs, but instead of a making a healthy moong bean salad at home for $3 of ingredients and 30min of their time, they order a $25 chipotle meal from door dash everyday at work.
