Dont overlook a fact the US branch is well aware of:
numbers in the US are down. Way down. if you take the "foreign field" (non native english english speakers) out of the equation, the branch feels there is a net decrease of 5% in the last five years or average of one percent a year. From the horses mouth on that..... They know they are losing people and are ok with it as long as those that stay are ferverant worshippers
