The passage does not deny the value of work itself. Its focus is the emptiness of endless labor aimed at gain when there is no clear beneficiary and no capacity to receive enjoyment from the fruit of the work.

Where interpretation differs

One difference is what “alone” most strongly means. Some read it mainly as lacking heirs (no son) and the nearest male kin (no brother), so the problem is: who will inherit or carry on the household? Others take it more broadly as a person without meaningful companionship or support, with “neither son nor brother” functioning as vivid examples of being truly on one’s own.

A second difference is whose question it is: “For whom then do I labor?” Some take it as the worker’s own unspoken realization. Others read it as the observer’s rhetorical framing—putting into words the question the scene forces, whether or not the worker ever asks it.

Why the disagreement exists

The Hebrew description is brief and concrete, naming family roles rather than using an abstract word like “friendless.” That leaves room for readers to weigh whether the emphasis falls more on inheritance (a social and economic issue) or on companionship (a relational and emotional issue). Likewise, the quoted question can be heard as inner speech or as the narrator’s implied commentary, and the wording works either way.

What this passage clearly contributes

Textually, it contributes a memorable diagnosis of accumulation without satisfaction: “eyes” that keep wanting more, paired with “no end” to labor. Theologically (as inference from the description and verdict), it portrays a kind of life that is not merely busy but distorted—work detached from shared benefit and detached from enjoyment becomes “empty” and “miserable.” It also sets up the next unit’s contrast, where companionship has practical advantage (Ecclesiastes 4:9).
