The 1990s were a time of great expansion in the arts in America. But Andrew Taylor wonders if we have too many new mouths to feed. “Perhaps what we have built together has outstripped the capacity of all combined sources to support it. Perhaps we are entering an era of contraction, merger, bankruptcy, and market adjustment. But the question still festers in my head: ‘overbuilt’ by what measure? Are there too many nonprofit arts organizations? Do they generate too much product? Are the organizations too large or rigid in their construction?”
