One has to be very careful about conclusions based on the assumption of someone else's ignorance.

There are a lot of people who spend lots of money doing something in a stupid way (look at big software companies), but even they have an underlying reason: it's difficult to pick good programmers and value them accordingly unless all your managers are also programmers (and who picked them?).

When you say, "The normal approach to X is stupid; we're going to do things differently," you have to understand how the normal approach came about so that you can avoid ending up there yourself regardless, and also so that you can avoid whatever problems it adapted to avoid.

There are situations when assuming by default that other people are reasonably intelligent is a bad or dangerous idea--while driving, for instance, or during basically anything involving casinos or Black Friday. But when a market governs a motivation as powerful as money and is sufficiently discerning, you'd better start really questioning whether those people are actually stupid or you just don't understand what they're doing.
