In germany - I think - blood and plasma donations are most commonly done with the DRK (German Red Cross). I might be wrong, but DRK is not a for profit organization, but “gemeinnützig”. Organizations with that status get controlled by the government for it, so they are non-profit. I think the 25€ are an incentive to come and donate, just as the chocolate and drinks and the small goodies, that you get there. And you only can get the money, if you go to one of the fixed DRK locations. If the DRK comes to somewhere near you (as they often do with churches, town halls, schools and universities) you don’t get any money. I can at least believe, that these two are monetarily similar for the DRK. If you come to them, they don’t need to pay for getting the equipment and people to you. And providing incentives for donating blood is in effect a good thing, as they are working, thus we have more blood to save lifes.
Ofcourse actors later in the chain are probably profit oriented. Though there I would see the discussion disconnected from the donation. It is more about if we want profit oriented actors in healthcare.
And - as always - the US healthcare system seems to do the worst thing possible every time. Sorry, americans, don’t want to bash you, but capitalism…
It will surely help significantly preventing a tactical nuclear strike from russia, though it won’t end the war. It is an absolute last resort trigger. Ukraine will be annihilated after they use it (Russia has way more nuklear weapons).
So somewhat good for them and OK to do so, though no solution and no substitution for western military aid.
