At the senior mgr level, your position in the hierarchy is highly visible to everyone and also in your own mind. The higher, the more visible. You are more likely to feel inferior (+superior) to other people across the industry. In contrast, the regular employee and contractors are not in a position to feel that much inferiority — /blissful oblivion/ means happiness and carefree.
Some would say the inferiority is a /part and parcel/ of moving up, so most people would willingly accept it. I think each individual reacts different. Some may be more affected by it when they move up.
Rivalry is another side of the same coin. It can get ruthless. I remember Mark in PWM.
Demotions and promotions are more intense than the annual bonus situation.
