For the youth, the indignation of most things will just surge as each birthday passes.

Taken at face value, the line suggests that in youth, feelings of outrage or moral indignation arrive in waves and can intensify with age—“surging” as each birthday marks another step into experience. It frames indignation as a near-default emotional response for the young: a heightened sensitivity to perceived injustice, hypocrisy, or disappointment in “most things.” The phrasing also implies a cyclical pattern—each year brings fresh causes for anger—hinting at the way growing awareness of the world’s complexity can fuel frustration before it is tempered (or redirected) by maturity. The quote reads as reflective rather than celebratory, observing youthful indignation as powerful but potentially overwhelming.
