>>20709067Take the example of car manufacturers. Every car company makes the majority of their revenue on parts and repairs. As expensive as cars are, people only buy one every ten years or so, which makes the sale of the car itself only a break-even transaction. This is also why new car manufacturers have such a hard time breaking into the market because while your selling cars for the first time, you don't have a consumer base that already has your car that needs to buy parts from you. Same principle applies to most manufactured goods in the US, they need to make sure that you become a consumer for life either by replacing the product itself or purchasing parts.
(and this is according to Elon Musk, who shared the story on why an automotive investor believed Tesla to be not profitable in the long term)
