Just a general comment: this was a great question. The responsibility for vocations begins in the home.
I am discerning a vocation and have been affiliated with the Diocese of Rockford, IL. Instead of hand-wringing, my diocese is actually rolling up its sleeves and going out to the flock and promoting and nurturing vocations. We have 3 vocation summer camps (one for Jr. High boys, one for HS/College age, and one for girls interested in religious life) that include talks from priests, religious, and nuns (for the girls camp), adoration, confession, and, of course, fun activities such as cook outs, camping, hiking, etc. The kids love it. We also have monthly meetings with prayer and topic discussions for young men interested in the priesthood.
Now, saying all that, the Diocese is doing something. Of course, joyful, orthodox parish priests have a huge role.
