Ok, I’m going to try not to overthink and stop with this.
I’ve maintained that while age is a primary contributing factor, it is far from the only one, and the others should be tended to as well. My hunch is that Rabbi Miller might be addressing the societal ills etc. rather than the age issue solely. AZ might differ.
But my having this hunch and speaking for Rabbi Miller may make me as presumptuous if not more so, so I should be asking mechilla too.
