'Someone' in the Bible

Is there anything about which someone can say, "Look at this! It is new!"? It was already done long ago, before our time.

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!

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.
