In my mind, your opinion is the epitome of capitalist thinking. You have an extremely low bar for the definition of lifetime impact. In a century, will "changing how household brands do business" be remembered, or rather the low-paid scientists who will have discovered the thing that will make nuclear fusion work? Admittedly, academic work is often a dead end. That's because it's high-risk, low pay. You're choosing the high pay, low risk path. It's almost certainly a better path personally speaking, but will people remember you for it? I think not, and nor should they.
