No offense, John, (seriously) but do you currently fly so many hours in
so many parts of the US that you can make that broad of a statement?

I only fly about 5-7 hours per week, but in the busy Northeast US
airspace I *always* hear pilots, both GA and airline, read back
altimeter settings. Additionally, I have heard quite a few exchanges
where a controller has corrected an incorrect altimeter setting
readback.

Personally, I always read back any number given to me by ATC if for no
other reason than to aid my own memory.
