I think the church puts itself wide open for criticism on the feasibility of its goals. But as for the motivations, I think it's not productive to spin that as arrogance or ignorance. I think it is more productive to recognize that the Catholic church is big, influential, and not amenable to compromising on what it sees as the word of God, and then attempt to work with or around the church from there. I suspect that the Catholic church, USAID, and others have more goals in common than at cross purposes.
