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?
Because then people who urgently need money do everything to get that money.
E.g. lie in that questionnaire. And you know who needs a lot of money? Intravenous drug users. Who tend to share needles. And have a higher risk of high risk sexual behaviour (both from prostitution itself but also rape, infections in their mucosal areas,etc)
