Without having seen the show, I'm not ready to condemn Christy (or anyone in her family) for her participation in this scheme. We're working from the assumption that when someone comes by a large windfall their loved ones should benefit, as well. And while that may be true for my family and loved ones if I won a grand sum of money, no one should expect to wet his or her beak simply because a relative struck it rich.
In fact, I read a study that of the lottery winners who report they're even unhappier after winning a lottery, a large majority are unhappy because their families won't stop pestering them for money.
I'll try to find that article again, but for more information about lottery winners and their lives, see this. You may be surprised by what you read.
