Nope. Their are humans. And (seeking) happiness is one of the most powerful motivators (if not THE most powerful one) for such beings. Also, happy people just produce better results. Especially if the way for them to achieve happiness is the route to better results. If you just want your coal mined, happiness of your workers may not matter much. As soon as you want quality output from any intellectual worker it will start to matter. (Though I'm pretty sure that it's true for any job with any level of autonomy and creativity needed, even if it's manual labour.)
