Or, take it for what it is, a quote from a movie.

But don't dismiss the merits of the idea. It's essential Risk Management[0], which is most certainly a relevant part of Information Security. Specifically, this is a form of Cost-Benefit Analysis (specifically, Qunatativie Risk Analysis[1]), a critical component in proper Risk Management; the reality is you cannot "fix" every issue.

Take a look at methods like Single Loss Expectancy[2] and Annualized Loss Expectancy[3]; you'll find that the Fight Club quote is very close to the real-world methodology. I cannot speak for the Automobile Insurance industry, but given Insurance is founded in Risk Management, it seems likely to be closer to reality than not.

Fight Club is referencing to a real document made by Ford, the "Pinto Memo"

That is indeed fictional, but the real world Ford Pinto that was based on is real [1].

The quote is resonant because anybody with first hand experience with the way "corporations" think internally about such matters KNOWS that this is EXACTLY how it plays out.
