It seems like a kind of tragedy of the commons. There are many people involved, and each one can reap some personal reward by cutting corners just a little bit ("I should get a raise because I saved the company X dollars in Q3 by reusing existing assets!"), but if enough people do that, and you get a little bit of bad luck, then you get a failure cascade that threatens far more money than anybody saved.
