Is it problematic that lawyers can be public administrators for estates in North Carolina?

North Carolina (and other states, too) allow lawyers to act as public administrators for estates in which the deceased has limited resources (indigent, usually), where there isn't someone appointed to act as administrator, where there is a conflict over who should serve as administrator, or a combination of these and other factors. Lawyers who do this do quite well financially, especially in populated counties. It does, however, raise the question: is it problematic? If so, how is it problematic? I can see many, many ways.
