Most people think that most arts organizations are self-sustaining and aren't in deficit, and that most artists make a very good living. And of course the opposite is true. No, I don't think so. I don't think they understand the ratio. Actually, corporate support is still not as much as what the individual givers contribute.
Foundations are a very small percentage of giving overall.
Individuals in the United States, like you and me, are the ones who sustain the nonprofit arts. You'll get a cross-section of the local donors. They take care of their own. To a certain degree. But it's getting harder and harder as expenses rise.
