Sorry - you repeat a myth and meme that has been proven to be incorrect.  
In fact, CARA, PEW, Vatican surveys have all documented through valid research gathering that the liturgical changes energized and retained catholics in the western world.  Expansion in the second/third world continues to happen (so much for your incorrect over-generalization)
What that research does prove is that Humanae Vitae decision created the context that began the exodus;  the clerical/episcopal sexual abuse scandal increased the exodus; and gender insensitivity.  
Finally, you appear to not understand that councils lay out principles that a committee implements.  But, documentation (i.e. vernacular) shows how quickly thousands of bishops who attended and voted at VII, returned home, listened to their people, and asked for vernacular permission from Rome.
No one who understands translation theory would agree with your last sentence - nor does Francis and almost all of the curial liturgy office.
