Organ egalitarianism

Edit: I just remembered that the egalitarian suggestion came from Philippe Van Parijs, and not Julien.

I attended a conference here in Reading the other week, and saw Julien Savulescu give an interesting talk on the issues surrounding having a market for organ trade.

Most of the talk consisted of responses to various objections you might have to the idea. But one interesting suggestion in favour of the idea was that we should endorse it from an egalitarian perspective.

After all, if organs become tradable for relatively large sums of money, then we've suddenly increased the wealth of everyone in the world by a large amount, regardless of their position now. This egalitarian windfall diminishes the gap between rich and poor.

Sure, organs would probably mostly migrate north and west. But still, money would migrate in the other direction, and it's not unreasonable to think that some people really do need a house (e.g.) more than their second kidney.
