A very sad, angry view of what has happened to American Catholicism over the past 50 years.  The Church has never operated in a vacuum, isolated from the social changes occurring all around it, although it has been all too reticent in her responses to it.  But the facts are (which I have the impression you will outright reject) that the decreases in Mass attendance, fewer vocations, and priests and religious leaving ministry were all happening long before Vatican II.  The targets of your blame-game are quite misplaced, and based - I believe - on some poor grasp of the realities of a century of Church history.
