Professionalization

As I read the articles on Archives, Administration and Records Management I was thinking about the issue of professionalization. Is it a good thing for the field to be professionalized? Does that push out the amateurs? Should there be a place for amateurs? Why did the historical profession in the academic organizations abdicate their responsibility for advocating for professionalization of public history? Is that another example of "shooting yourself in the foot"? If it is important that the people who direct or museums, archives, historical sites etc are historians, and not just technicians, then we should advocate for this? What does training in history do for these administrators and records managers that could not be done by someone trained in public administration or management?
