Two Minnesota theatres are going out of business. That’s sad, writes Dominic Papatola, but not really. “I’m a believer in what one arts consultant calls the ‘limited life organization.’ Not every arts group that pops up should grow into a major institution. To be brutally honest, Minnesota’s historically generous philanthropic support for the arts has kept some groups on life support longer than would be considered merciful elsewhere. We live in a new age of artistic Darwinism: Some groups will expire as the energies of their founders fade. Some will not earn audience support. Some will not have the hustle it takes to find funding and endure.”
