In our society, it is the people who have power who manage to get things done. The type of power — financial, political, or even brute force — might change, but the use of it to accomplish goals does not.
We see examples of influence all around us. A business leader may use connections they have to make deals. Or someone who holds political office may use their position to enact legislation. Yet another example is a popular person exercising their social connections.
That power might be used for personal gain, or it might be used for societal gain. How it is used may be determined by the character of the person with the advantage. Conversely, there might be social or legislative checks on that power.
There is also a certain influence that comes from collaboration. One person may not be able to do much in isolation, but if that person can recruit a hundred others to help them, their reach can expand drastically.
Do you see power being used around you? How? Who has it? Is one kind more effective than another?
