On active duty I served with several legitimately married priests whose wives enhanced their ministry. Together they provided a richness and wisdom that we celibate males will never have.  There is no reason why priests have to serve the church only in the manner which we are familiar with in the US such as living in a rectory. There are countries/cultures where the life of a priest as we know it is not the custom.  Priests can earn salaries in jobs that are compatible with priesthood, e.g., doctors, teachers, business owners, public service, etc. 

While we will always need priests who serve to teach, lead commnities in prayer, etc, it is not necessary that there be a male only "priestly class" or "caste" as we have now. Service as a priest need not be a permanent lifetime commitment.  There are issues that need to be addressed, questions to be asked, serious respectful dialogue to take place. The Spirit is at work among us, and we don't have to fear questions and dialogue.
