Get rid of the archaic law that prohibits financial compensation for organ donation. Many more people would designate their organs for donation if they knew that they would cover the cost of a funeral and maybe even provide for their family for a short while.
Now, before the rabid Common haters start screaming about "He's worried about riches beyond the grave," rest assured that I AM an organ donor....but not everyone is a nice guy, like me. Some need an incentive, and right now there is absolutely no incentive.
Another option, FAR more practical to me, as I'd be alive to enjoy it, is giving a discount on the drivers license fee for organ donors. Georgia tried it for a few years and saw a forty-percent rise in those designating themselves as organ donors. (They also offered the option of your providing your own photo instead of settling for one of DMV's mugshots)
Back to selling organs, a sad fact is that there are far more people who are waiting on kidneys than can be provided for through cadaver harvesting. Allowing healthy people to sell a kidney would close that gap and allow them to weather difficult financial times.
Sure...it's a gamble, and I wouldn't do it, but if you want to increase the number of donors you have to think outside the box and start making the act of organ donation worth something tangible in THIS life.
