I don't know that 'hesitancy' is the right word. It's just fundamental that people in power use it to seek more power. Even a small initial power imbalance will eventually lead to a large intractable one. Happens at pretty much at all scales of social (political, economic, etc) interactions. The only solution I see is to set up systems that make power accumulation more difficult coupled with a constant struggle to rebalance when it inevitably lopsided.
