That is due to extreme levels of inequality in the US and one of the stingiest welfare systems in the whole developed world. It is not due to food prices. If that was the deciding factor then Norwegians and Japanese would be starving.

A lot of the low food prices in the US also contribute to this poverty. The low prices come at the back of people in the food industry doing long days for shitty pay. If the “solution” to people not getting food on the table was to keep pushing food prices down then one easily end up in a situation arguing against minimum wage and workers rights.

One has to look at the whole system and not just a tiny sliver of it.
