Not inflation, the price has increased far beyond the inflation rate as McDonald’s struggled to stay profitable and adjusted their strategy and posture (mccafe era).

You may not know this but when it was made McDonald’s was vastly cheaper than it is today. Double cheeseburgers were just a single dollar. It’s somewhat difficult to achieve a multi ingredient hot meal for that price with groceries and it requires doing meal prep and reheating. Today’s McDonald’s is way more expensive which completely invalidates the case for eating it at all outside the breakfast menu (actual eggs).
