"Agency refers to the capacity of individuals to act independently and make their own choices..."
If we consider agency a defining aspect of the human condition...
Administrative points:
1. The graph is unit-less, for discussion purposes only
2. One may sacrifice in one tier of agency to reach for the next, though influence as tiers are skipped is heavily diminished as foundationally each depends on the next.
3. This is not a value conversation nor a suggestion that any progression [beyond the black line] is a necessary good.
------------------------------------------
Consider the characteristics (and sacrifices inherent) of each levels influence, the people in your circle who fall into each, and where you hope to land.
-------------------------------------------------------
First, the black line
Slaves to their own emotions, without capacity to right a wrong or correct the sail on their own ship. Birth until death, blown on whatever winds come their way, without knowledge of the ships workings. Save your pity for the weak.
Second, the green line
Hopefully the starting point for most. Having figured out space-ship-you, self-knowledge can embrace luck or otherwise tack in the face of a head-wind.
Third, the orange line
Commonly uncommon [depends on your bias and zip code]. Plugged in to the system is the only way profit is realized, and currency accumulated. Not just to maintain position on the treadmill, but enough to inch forward incrementally. Reinvestment, no longer just an option, but a quality of the present, building the train tracks just ahead as the train chugs forward.
Fourth, the blue line
The first stage where your influence has started to outlive your own mortality. Your grandchildren may not remember your name, but [attribution suspended] they will feel the benefits of your legacy. Perhaps a connecting line should've been drawn up from the blue/yellow/green or black lines.
With enough gravitas and power, agency is extended into one's relatives - your personal agency empowering and affecting theirs.
Fifth, the purple line
Again, non linearly, most will have agency affecting their community - positively or negatively - independent of their personal agency. A community is a sum of its individual parts.
However, the grander degree of notable agency demonstrated in personal capacities will reflect on the degree of its blessings imparted to the community downstream.
Sixth, the red line
Very few will have agency that can affect a global legacy, as it takes a tremendous amount of agency, luck, and [let's face it] generational exploitation to reach such a level. Consider your favorite neighborly technocrat trillionaire [USD].
-------------------------------------------------
Your mobility and relative agency in each level will wax and wane with a multitude of factors not discussed, notably including age and economic status.
You don't pick your parents, don't rebel, make the best of your hand dealt as it was.
