Adam Clarke on Proverbs 28:16

The prince that wanteth understanding - A weak prince will generally have wicked ministers, for his weakness prevents him from making a proper choice; and he is apt to prefer them who flatter him, and minister most to his pleasures. The quantum of the king's intellect may be always appreciated by the mildness or oppressiveness of his government. He who plunges his people into expensive wars, to support which they are burdened with taxes, is a prince without understanding. He does not know his own interest, and does not regard that of his people. But these things, though general truths, apply more particularly to those despotic governments which prevail in Asiatic countries.
