Time for the government to operate grocery stores selling staple items. No need for them to get into luxury goods and snacks, but a not for profit business for grains, flour, fruits, vegetables, dairy and bread etc would be nice. Keep those costs down and they can create additional measures to stabalize costs.

Like Co-op grocery stores but an actual co-op with better prices.

Maybe give extra food expiring to food banks could help a ton too, instead of being evil and throwing it away.
