Hey, nice job with the name calling. You're great at arguing!
But you didn't exactly answer my question. You described a concept in economics, yes, but you didn't answer the basic question: why would the companies profit if they started selling an inferior product and people stopped buying it as a result? If gear companies sold your inferior helmets, then the company that still sold good helmets would dominate the market. This is called "competition" and is something you need to understand just to get into any of those business schools.
