> Companies with bad cultures try to motivate employees with fear and intimidation, or simply fail to motivate them at all, and everyone wastes their time playing video games or whatever. Not surprisingly, those rarely do well.

This seems like it could be a chicken or the egg problem though. How do you know that good culture isn't a byproduct of success. If Google stock were tanking, how do you think the culture would look? I honestly don't know.
