Respectfully disagree. My grocery bills, which content pretty much don’t vary that much week to week have gone up slightly the past year. Have you been pricing fresh meat lately? Gas prices have dropped, so your overall premise is correct.
Your grocery bills may very well have gone up over the past say, 2 years, but one problem here is that national inflation policy has to consider everyone's bills on everything along with of course your bills on just groceries. The other problem is that you're not posting any dates and numbers, just your sense of what's happening. That's the key because the misunderstanding here is a number/feelings thing.
Everyone feels that we got runaway inflation so folks that want votes or run a political forum use that feeling to their advantage. Numbers are what they are however and anyone who say, insists the price of oil is up and starts drilling in an under producing field will lose money no matter what everyone feels. Same w/ real estate. Same with anything else w/ falling prices.
