Since “power” is [in the US] generally associated with “evil,” the people in the US who have actual power do not and cannot think of themselves as having power.

However, there are euphemisms for it. Perhaps the most common is “responsibility.”

A good way to find the most powerful people in the US is to find the most responsible people. No one in the US is scheming for power. A lot of them seem to be working for change. No one in the US is brainwashing the masses. A lot of them seem to be educating the public. No one in the US is ruling the world. A lot of them seem to be making global policies.
