Theri food budget is like any other person’s, except that they are poor, if they waste a dollar on a food item then it is a dollar wasted from their limited food budget, just like anyone else on a limited food budget, if you spend carelessly then you come up short at the end of the month.
For the chronic poor their entire lives tend to reflect their IQs and impulse control, they are likely to eat pop-tarts for breakfast not a cantaloupe and oatmeal, chips and hot dogs probably have a larger role in their diet than does Obama’s arugula salad.
As far as Whole Foods, I asked you why you don’t mention them, it is always Walmart that you use.
We have what used to a historical impossibility - fat poor!
