Giving to non-metropolitan arts

A debate in the UK is being waged over the challenge for arts organisations outside the capital to find wealthy patrons.  http://tinyurl.com/39zglt2   Leading non metropolitan institutions argue that, “Experience suggests that most wealthy private donors have chosen to associate themselves with national arts organisations based in the capital, notwithstanding the excellent artistic contribution that organisations such as ours make.”   I wonder whether the truth lies more with the failure of those arts organisations outside the capital to invest in philanthropy than the lack of regional wealthy prospects.
