Throughout the Suits season, Louis Litt seems to need constant recognition from his colleagues. He seems to feel inferior to other senior partners like Jessica and Harvey (especially Harvey). He feels insecure about himself and lacks self-confidence.
Why does he have this "inferior" psychological issue, given that he was revealed to be the richest person in the law firm despite holding a more junior position (watch Season 6 episode 1) compared to Harvey and Jessica? His bosses were somewhat embarrassed when they learnt how rich Louis was. Logically, his bosses should feel inferior and not him. Louis behaves like a "loser" when he is actually the biggest winner of the firm.
