I should have used more accurate language 'primarily driven'. I've known a bunch of doctors (my sister's partner is a doctor). They tend to list helping others as their primary motivation, with fulfilling a childhood dream as another big one. Financial rewards for a specialty sure, but not for why they got into medicine. I don't know many bankers. But I'd guess their primary motivation will be different. Sure they might enjoy something like analysis. But in the end of the day, you could be an analyst for a conservation NGO. Being a banking analyst attracts people with a specific set of financial desires.
