Showing that people are willing to pay a price does not make it equitable. You have to account for power dynamics and market conditions. I believe the original question was whether there was a relatively even or fair split of 'profits' from the current setup. One could make a case for this being even, and also for it being somehow relational to investment (blood from the giver, r&d + logistics from the receiver). Your 'answer' glosses over all that.

You're welcome to "make the case" for whatever you want, but this comment suggesting it's something in anyone's control belies what's really going on. The price system and "profit" splits aren't something any one entity (plasma doner nor company) sets down and decides. It (like most prices) is an emergent phenomenon. You might as well "make the case" the morning commute from downtown Chicago up to Evanston should be less than 35 minutes, it's pretty much irrelevant as to how it turns out.

I think you misunderstood me entirely.

I wasn't saying it was in someone's control. I was discussing analysis of the system as it is.

In that case I agree, it's certainly possible to analyze it, and market forces (number of firms collecting donatations etc) probably has a lot to do with the price, along with laws, alternative opportunities for doners, technology, how much it hurts, etc.
