^^I don't think Miranda chose her job because of "prestige." She chose it because she's a career scientist, an explorer. That's fundamental to who she is. Her goal isn't to advance her career, it's to discover new worlds and new mysteries of the universe. That's been her life's work, her identity, since long before she became a wife and mother. It's not just a career, it's a calling. Just as it has been for Kirk and Spock and Picard and Riker and so many other Trek characters.
