I disagree that there are never a sufficient number of clerics and installed acolytes...its more a question of getting the people out of Mass in an hour or less and giving lay people something to do.  You don't think the goal is to one day phase out EMHCs?

As for the EF, there will always be people who discover and appreciate the beauty and riches of our Catholic tradition and the Mass that nourished our forebears in faith. In the words of the pope emeritus: "There is no contradiction between the two editions of the Roman Missal. In the history of the liturgy there is growth and progress, but no rupture. What earlier generations held as sacred, remains sacred and great for us too, and it cannot be all of a sudden entirely forbidden or even considered harmful. It behooves all of us to preserve the riches which have developed in the Church’s faith and prayer, and to give them their proper place."
