Like most monopolies, benefiting from inertia and aggressive mediocrity.

I know of a parish (in the Fremont, CA area) which renewed its liturgical practice, to the point where Sunday Mass was making intentional disciples out of lukewarm Catholics.  At the request of a couple of dozen disgruntled families, the religious order running the place replaced the priest after 11 years of a 12 year term with an ideologue backed by that faction who threw out all of the renewal in a month's time, proving once again that it's far easier to destroy than to build.

The first thing done: shutting down the 1 Mass (out of 9 on Sunday) where things were being done by the book--the one producing most of those intentional disciples.  The second thing: hardbound missals from Corpus Christi Watershed were put in the closet (or thrown out) and replaced by Breaking Bread.
