I've always rolled my eyes at inflation because clearly, it's worse than the basket of goods they use to monitor. Groceries probably get incentives to keep bread, eggs, etc. prices somewhat regulated so the inflation number is muted. https://en.wikipedia.org/wiki/Goodhart%27s_law

Many of the inputs (farms, oil) are heavily subsidized already. Meat, milk, etc. but I'm sure they account for that in some way.
