I have received a somewhat unusual vaccination and my antibodies were valuable to a drug company for a while. They were paying 120$ for plasma for a while and you could go 2x a week. The plasma center, like most, wasn’t in the best neighborhood and the cash was doled out be an ATM like machine when you were finished. Well 120 took a hell of a lot more “kachunks” that 15 did and by the time you got your cash there was a whole room full of pissed off desperate folks staring at you. Not that fun.
I have had to sell plasma to make ends meet in my life and I know what those people must have been feeling watching some kid in nice clothes get paid 10x what they were for the same unpleasant procedure. Fucking rough. I used the money to buy a house. They would be lucky to get a groceries out of the deal
I mean I was able to save almost 15k during that year which was a suitable down payment on a 100k ish house. which wasn’t hard to find in the city I lived in circa 2005. It wasn’t anything to crow about but it beat renting.
