The auto industry are the razors, what about the blades? Looking at top US exports for 2022, I see: Refined Petroleum ($138B) Crude Petroleum ($118B) Petroleum Gas ($116B) Cars ($57.5B) Integrated Circuits ($49.8B) Some amount of that refined and crude petroleum isn't destined for automotive gas, but I'd be a fair fraction of it is.
