In Pakistan, impoverished farmers who remain heavily in debt largely thanks to an economic system that enmeshes them in massive debt have taken to selling their kidneys to outside markets, leading Pakistan's media to dub the country a "kidney bazaar."
CNN's article on the problem is fascinating: one one hand, Pakistan's kidney market doesn't appear to help farmers very much: paid price for kidneys remains low and, even worse, many people who sell their kidneys to help pay off their debts find they are no longer robust enough to work their farms, which results in them amassing even more debt.
But on the other, there's a strong argument that selling and buying kidneys (which is illegal in the States) is the sort of thing that should be encouraged, to give sick patients who need a kidney a second chance at life, unlinked to the arbitrary fickleness of their place on an organ transplant list.
