Dollar stores are the new neighborhood "outlet stores" compared to outlet stores of yesteryear (remote locations for not much/any savings). They're actually glorified convenience stores while also not being proper substitutes for grocery stores in food deserts. Most US grocery stores are also now rip-offs like convenience stores were, while big box stores are somewhat savings stores now... f'kin' turbo inflation.

I don't know about the feasibility of government grocery stores, but I'm pretty sure the entire food supply chain would benefit from massively changing to the employee-/customer-/supplier-owned co-op model and get megacorps and private equity out of the normalized deviancy of predatory money extraction for essential goods and services.
