I agree. The state of even Charedi Jewish leadership in America today is bad. He may be a lonely voice, but he's following the Talmud's injunction: where there is no man, he is being a man.
There's an organization called the Union of Orthodox Rabbis of the United States and Canada that is very similar to Rabbi Levin in their positions and worldview, and I believe they're the oldest organized rabbinic body in the country.
Strictly speaking, the chareidi Jewish leadership in America, represented by Agudath Israel and others, is doing fine, unlike the politically correct orthodox Rabbinical Council of America.
The late Lubavitcher Rebbe was insistent and outspoken in urging Jews to take active interest in halting the moral decline of the general culture.
