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?
Czech Republic, it has some requirements like it has to be voluntary, in good faith…
But basically you get 3000 czk write off per donation max 12 000 czk per year (you can donate every 3 months).
There are some more benefits into this, mostly from private companies, insurance groups or state agencies, aimed to motivate people to not be dicks.
