If you want to see a true plummeting in Mass attendance look at the drop from 80-90% Mass attendance with the old Mass before Vatican II to the 20% Mass attendance with the new Mass after Vatican II. Catholic worship has gone off the rails and we need to get it back.
Yada Yada Yada!
With that being said, I usually drive to another local parish instead of my closest parish, just to find a Novus Ordo Mass that I can live with and not be annoyed with. Which is pretty much the lot of all right thinking and knowing Catholics.
