If I could trade a kidney for a way to pay for the Master's degree in Clinical Social Work I want? I would totally sign up to sell a kidney.
I'd be willing to live with the bloat and occasional random pains. Same if someone wanted a partial live liver-they can now cut the liver tip off, stick it in someone else, and have both the donor and the liver stub regrow a whole liver...it's a risky op on the part of the donor, but I'm tired of being poor and spending all my energy just to pay bills, such that I have little/no time to go work on the degree (I'm @ work now...I'm a guard in an organ and tissue donation organization.).
(reminds me...FAFSA...urgh...)
So I wish I could sell my own kidney, quite frankly.
Something that would push up supply would be an "opt-out," instead of an "opt-in", such that unless you otherwise specify, you are automatically considered to be an organ and tissue donor.
I see religious objections, but I think it would help save/prolong lives.
