Just right off the top of my head, I hadn't anticipated being generous to people who would only be taking the generosity if it was by taking advantage of it. I think that's what it's really about. It's like someone who says, here you go everyone who needs money, here's one million dollars to help you out! And a Harvard MBA catches all the money, and says, cool, I'm going to go get a Hummer and put a downpayment down on a home in the Hamptons. As a generous person, you want your generosity to go towards those in need. Can you imagine a buddhist monk, saying, "anyone is welcome to come and enjoy our Tibet", only to have China come and plough down the mountains and make a Disneyland China themepark? How do you think the selfless monk would feel about his actions in that case?
P.S. Just for clarity, I'm a guy, and my SO is a chick, because maybe I think I saw some of that switched around in your posting.
