You may be right that this is a golden age because, indeed the management functions within the museum buildings have improved. I think all periods of transition are so messy while they are occuring that the humans swept up in those transitions often have trouble seeing the silver lining. And progress is usually not a straight ascent but two steps forward and one backwards in nature. I still think the largest problems for non-profits in the US is that they are the only segment of society where the final decision-making authority (trustees) rests with hobbyists who have never worked in a non-profit. They usually don't really understand education, culture, art or non-profit accounting.
