Shared experience is good for communication. Disparate experience is good for learning. A star wars joke can cut a 20 minute discussion to zero, just because "That's great kid, don't get cocky", communicates what might take quite a while to express. It's a really delicate balance. "culture" can mean speed. I don't know of many organizations that do this, but it's certainly possible. OTOH, that locks you into a specific worldview, and can make you blind to problems. Diverse backgrounds make organizations much more aware, but less able to communicate that information quickly. An example is when someone picks up a new language, and they try to explain the new constructs and philosophies behind the language. It takes a long time to explain why mapcar is cool.
