Allow living donors to sell kidneys

I think it should be legal for a adult who is healthy to sell their kidney. The cost of care for a person needing a kidney is at least $50,000 a year and thousands of people die every day waiting for a kidney. I do not feel it is imoral because there is a great need and if the price is restricted. I do feel the law should allow for some profit for the donor because after all they will be taking the risk of needing one themself someday, along with the other problems they could have. I've read many reveiws from doctors who feel this could save many peoples lives, plus cut the cost of health care. So please read up on this and sign this petition.
