Do you think that volunteer organ donors should get preferential treatment over non-organ donors in regards to receiving organs?

I'm not sure if this is a question of principle or policy. Let's start with the question of principle. Certainly, volunteer organ donors deserve moral kudos, but should they get to move ahead of others in line to receive organ transplants? That really depends on what the principles should be guiding the distribution of this scarce resourse. Should it be responding to the most urgent medical need? Maximizing life expectancy? Maximizing contribution to social happiness? Something else? If, say, it was giving priority to most urgent medical needs, then I don't see why preference should be given to volunteer donors. Perhaps the thought is that the benefits of a practice should go disproportionately to those who contribute to the practice, for, according to this principle, volunteer donors contribute more to the practice of organ doantion and transplant and so deserve priority. Perhaps being a volunteer donor could serve as a tie-breaker among transplant candidates who were otherwise equally well...
