Given the make-up of our current USCCB, I am not at all sure I want the Vatican to decentralize power to them.

I think this is a chicken and egg problem.  I can see that in some parts of the world, a model that depends on an educated, informed laity may not work.  But it should be obvious to the PTB's that the current all male/hierarchical, bishops as princes-who-must-be-obeyed model, doesn't work in places where there is an educated, informed laity.  Before we talk about decentralization of power, we need to talk about who should hold power and how power is decentralized from the male clerical/hierarchical model to a more inclusive model - women and lay people as part of the power structure.  

More, before talking about decentralization, there needs to be discussion of mechanisms of oversight and management of bishops - which simply do not exist.  Very important that this not be solely invested in a bishops conference, which can act as nothing better than a good ol' boy's club.
