True, people read more in the past, but that's a function of societal trends, not anything the Church has caused.
Then how is anybody to know what the Church really is? Those seminarians might do the reading, but there is somebody right there to make sure they don't get the "wrong" idea.
No, I don't expect every college student to immerse himself in the subject. I think the Holy Ghost will lead those whom he wants, on the path he wants.
I think it would be nice though if others with just a curiousity could get a traditional feel of the Church through their own efforts, because they will not find the Church through the regular channels.
That's just not so. I spent 14 years in Catholic schools and colleges, and was never once introduced to the Fathers. Until well into adulthood I never heard so much as the names of Basil or Athanasius or Chrysostom. I could not have told you a thing about Jerome. When I visited Canterbury (aged 21), I was astonished and confused to hear that "Augustine" had been bishop there. Whatever patristic knowledge I've acquired is late, incomplete, self-taught, and has been gained in spite of the gross negligence of those charged with giving me a Catholic education. I defy you to claim matters are any different today.
My son, a senior in high school, is just now finishing The Glories of Mary, by St. Alphonsus Ligouri, sink. He's in a study group with about two dozen of the finest Catholic young men and women you would ever care to meet and they gather every week to read and discuss the best our 2000 year old Tradition has to offer.
They are the future of the Church. They'll be the movers-and-shakers in the years to come and there are many more like them out there.
Be afraid, sink, be very afraid. -)
