NeutiquamErro, to which question are you referring?
Health, take a remedial reading course. I wrote that the rabbanim exercise judicial review (although if you look at the responsa literature they also exercised judicial restraint, especially when the case involved an established minhag).
Brisker,
1. I can say the same thing about you bringing proofs from your community.
2. Regarding Rav Soloveichik, I can counter-claim that rabbanim who said otherwise were influenced by the clerical parties in Europe. In any case, he was very definite about listening to rabbanim on halachic matters.He even wrote an essay on Korach’s rebellion called “The Common Sense Rebellion against Torah Authority”.
3. Rav Lichtenstein has an essay on the concept of daat Torah which can be read on-line. It seems to me obvious that just as one does not bring in a plumber if one has an electrical problem one does not ask a rav about economics (unless, of course, he is Rav Prof. Israel Kirzner or someone similar).
4. I do not know how much of a source Artscroll books are. In fact, Rav Moshe Tendler was very upset with that bio as it presented Rav Moshe as one-dimensional and did discuss the way he acted in his personal life. I also do not know what is meant by “running” Klal Yisrael. As I posted, the rabbanim set the legal and moral parameters. This perforce limits the secular professionals. For example, it might save a great deal of money to put everyone age 60 and up on an ice floe and send them out to sea but obviously the rabbanim would paskin that they must find another way (full disclosure: I am over 60).
