OooKaay. So who's been payin' the difference since 2007? DSO balances its budget for first time since 2007

Isn't it mostly rich, suburbanites who attend these concerts?
Why should the bankrupt city of Detroit divert a penny from things like... say STREETS, COPS, LIGHTING and give it to folks who want to foo foo at the symphony????
