> If people are willing the give a unit of plasma for $7.50 and supply is meeting demand, it seems precisely equitable. The US actually provides 50% of the world's plasma supply, because there are more people in the US willing to donate under the current system than there is a need for it, whereas most of the world (which does not pay for plasma donation) has an ongoing shortage. Plasma, like whole blood, also has a relatively short shelf life and cannot be donated on an as-needed basis, so it's preferable to have more than you need, since you never know when there will be a natural disaster, etc. I've donated plasma. I think the whole process, from the moment I walked in the door to the moment I left, was about two hours. I read a book the whole time and they paid me about $100 (I don't remember exactly how much). It was pretty easy, and I'd do it again if I could.
