Power is really that addictive. In ancient cultures, those who hoarded wealth were thought of as mad or of poor moral character, and there are modern psychological studies that show that anyone who is given power without consequences will abuse it and begin to believe that they are somehow deserving of the advantage.

The problem this time is that the ultra-wealthy have so much of the wealth that they can buy elections and control governments across the world, and no-one near them dares be anything but sycophantic, except their similarly-vicious billionaire peers.
