Some recent posts have mentioned how difficult it can be to find a good drummer (links provided in the above-referenced question). The tone of those posts was that the rarity of good drummers is a "truth that is universally acknowledged" (à la Jane Austen). (But I wasn't aware of this before reading those posts.)
I don't want to get into an argument about whether it's true or not (that it's very difficult to find a good drummer). I want the people who believe that good drummers are hard to find, to help me understand why they are so rare.
My question is about to be closed. Can folks please help me formulate my question better, so it doesn't get closed, and so it gets some helpful answers?
