The reason why artists don't sell all tickets to rich people is because they think poor people deserve nice things too, so they lower the price. But surely all poor people deserve nice things, not only your fans? Why not sell tickets to rich people and then donate the proceeds to help poor people? It seems to me that this way everyone wins: artists take the same monetary hit they would've taken anyway if they lowered the price, but the difference goes to poor people instead of scalpers.
