NO.
Human body parts and organs should be donated only.
IMHO poor fellows that are in a waiting list for an organ transplantation must have a chance to survive.
What an idiotic argument?
Just because the poor fellows are dying from organ failure, you want the rich patients also suffer the same fate? I have a better proposal. Make organ trading legal, and then impose a 25% tax on top of it. Use the tax revenue to help some of the poor guys survive. In this way, you can save the life of one poor guy, for every 3 lives saves from the rich sector.
