Yisro said to Moses, “What you are doing is not good. Being the sole judge for a population of millions is sure to exhaust you. Therefore, develop various levels of judges to assist you.”
The Midrash says that because Yisro advised Moses to select capable people as judges, he was rewarded by having a portion of Torah named after him.
But Yisro’s statement began with his pointing out to Moses that what he was doing was not good and would exhaust both him and the people. Why does the Midrash not mention this?
It is because anyone can criticize and point out faults, but that does not resolve the problem. Yisro is praised for the positive, constructive advice he gave.
Anyone can criticize. If you cannot suggest a solution, it is best to keep silent.
