Ecclesiastes 2:21

2:21 For a man may do his work with wisdom, knowledge, and skill;

however, he must hand over the fruit of his labor as an inheritance

to someone else who did not work for it.

This also is futile, and an awful injustice!

Ecclesiastes 4:8

4:8 A man who is all alone with no companion,

he has no children nor siblings;

yet there is no end to all his toil,

and he is never satisfied with riches.

He laments, “For whom am I toiling and depriving myself of pleasure?”

This also is futile and a burdensome task!
