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!

I saw something else on earth: In the place of justice, there was wickedness, and in the place of fairness, there was wickedness.

God gives a man riches, property, and wealth so that he lacks nothing that his heart desires, yet God does not enable him to enjoy the fruit of his labor -- instead, someone else enjoys it! This is fruitless and a grave misfortune.
