Fund Raising 101

When you're trying to raise money for the less fortunate, why would you target the less fortunate to attend an event or fund raiser? Um...maybe targeting a crowd that has more disposable income might help in the cause? I think this is one of the big things that get to me when I attend "art for art's sake" fund raisers. Most of the time, I see artists and other supporters who don't necessarily have the disposable to allow them to give.
