Charles Ellicott Commentary Proverbs 28:16

"The prince that lacketh understanding is also a great oppressor; [But] he that hateth covetousness shall prolong his days." — Proverbs 28:16 (ASV)

A prince that lacks understanding is also a great oppressor. —Thereby losing the love of his people, and at the same time impoverishing them; thus killing the goose that laid the golden eggs. He also by his misdeeds draws down upon himself God’s anger in the shape of an early death. Compare the woe pronounced upon Jehoiakim (Jeremiah 22:13 and following).
