Groceries have about a 2% markup. If prices were not raised due to inflation, you would see shortages at the grocery store. Do you enjoy shortages? Because I don't. If the government starts putting price controls on shit, you're going to see rapid deterioration real quick. As an example, the governments might say that a grocery store can only sell Oreos for a dollar. And okay, that's fine. Except that grocery store won't have any Oreos when you want them. But you can go to your local drug dealer and get Oreos for three dollars if you wish.
