"Back then, people would go to Confession every week and Holy Communion once a year... nowadays, it's the other way around."
Well, if even that. If they would confess once a year, they would at least live, according to the Council of Laterans, as good Roman Catholics, for they would still fulfill the 4th law of the 5 articles of the Church.
But don't be fooled. Among trads and in trad chapels this might be the case, though most people there confess more often, but in Novus Ordo parishes the normalcy is, that only 2-4 %, mostly elderly, go to Confession, well, once a year, probably at Easter, like my dear grandmother did (and she complained, that the modernist priest would be so liberal in Confession; note, he had been a co-seminarian for many years with the founder-priest of our local traditionalist church!). But I agree, that it is a bit Jansenistic or even quietist, to only confess once per year. It is pride too. These days we often sin by our views.
The nice thing I find, that in the Middle Ages, even at a Mass said by one priest for a few faithful in some crypt, they would still have at least one cantor and one altar server.
