Not exactly sure what you're suggesting, but I'm not assuming the poor don't eat. On the contrary, I'm saying that the poor spend a greater percentage of their income on food and rent, and that overall price inelasticities of food/rent would result in inflation for that class of goods.
Let me put it this way. If you were the only grocer[1] in the neighborhood and you knew that everyone in the neighborhood just got a 10k raise, would you not consider raising prices? Or, put another way, if you're the only grocer in the neighborhood, and everyone gets 10k/yr of free money, and that induces, say, 10% of your workforce to quit for various reasons, then you have to pay more for labor and pass the costs to customers. Either way, food prices rise.
[1] Note, that's not improbable in many poor areas.
[2] I'm just armchair speculating here... so, like I said, I could be way off base.
He is saying that the actual demand (amount of food people buy) is not going to increase much, so the whole argument rests on you being the only grocer -- and if you decide to increase your prices that much, that would only result in either (i) your former customers now carpooling to go to nearest Walmart, or (ii) more grocers opening nearby (since the grocery business in this neighborhood suddenly became much more attractive).
