I’ve been a blood donor for most of my adult life, and have donated about 30 liters. Where I’m at you get a token donation and a thanks for donating, but someone mentioned that in the US you get paid quite a lot depending on the quality and the blood type.
I have a fairly uncommon blood type (about 10% of the population) and a blood count of around 150.
So, how wealthy would I have been if I had donated my blood in the US instead?
Especially because at school we learn that it is important to donate, blood and organ, because it helps other people and maybe can save lives, not because we can take profit out of it.
