Food production is one of the very few things the US government has been handling well. We give out tens of billions in subsidies to farmers every year to artificially inflate the food supply and have a nationwide SNAP program to help low income families afford food. As a result, we produce far more food than we actually need and far more than we would in a free market, allowing the US to be a major exporter of food globally and ensuring we have enough redundancy built into our food supply that the US will be the last country to starve in a famine
A little further implies a minor inconvenience as if it's not a real problem. No, food production shouldn't be tied to number of grocery stores. Not sure how you think they're implying that. It is a logistical problem that could be solved if people weren't more worried about profit than human needs and suffering. Zoning laws probably also play a role.
Because the USA is huge and has areas that are more remote? Providing abundance to areas by certain priorities such as population still allows food deserts to exist.
I mean I guess I could be wrong but are we really going to talk about the food distribution system like we know about it?
Remember that time they had too much milk and were like "Lets make cheese!" And then they had too much cheese so they put it in a cave and slowly gave it away for decades.
