You're conflating inflation with market gouging. Why would your local grocery store drop the price of milk? What's the incentive? You probably haven't stopped buying milk, I bet none of your neighbors have stopped buying milk. In most of the country you have at most 2 grocery chains that are probably mega-chains, and they have no incentive to compete with each other.
What you're seeing at this point isn't inflation, it's market gouging and unless you're onboard with the government either breaking up these oligopoly's or setting market prices, nobody running for office is going to be able to "fix it".
