Yes, but also the bees make too much honey if they don't need to swarm because you manage the hives better than nature (which doesn't manage them at all), so yes it's symbiotic. We split them (reproduction). We give them room so they don't have to move. We help them stay warm in the winter and cool in the summer. We help them stay disease-free. We help defend them from predators. They don't "know" any of this, naturally, and we have bread them, yes, to be calm -- except of course for the recent africanization of bees which basically undid that breeding, though we still work with them anyways (and we're trying to breed the aggressiveness back out).
