In the absence of substantial Scandinavian-style subsidies for classical music, what are the best ways for orchestras to stay afloat?

I think a lot of us would probably agree that big subsidies of the kind seen in places like Scandinavia can be hugely beneficial to classical music's accessibility, affordability and popularity. This kind of subsidy seems to be much more effective than many other, smaller measures and gimmicks. Every time one of those smaller measures is proposed, someone always seems to suggest that the real solution is to have greater subsidies. While this may well be true, unfortunately not all of us live in countries with governments that are hugely generous towards the arts. So in the absence of that kind of state support, what is the alternative? What else can orchestras do in order to remain financially secure? Should they continue to court more private and charitable donors? Or alternatively, should they abandon these measures and lead the charge against austerity in the arts, and try to get bigger subsidies? Let me know your thoughts.
