Opposite of that. People who have been in poverty for a long time know that plasma donation is one of the ways to keep the lights on or be able to afford food that week. After repeated donations, you are left with a buildup of scar tissue.

Those who haven’t suffered in poverty may donate occasionally for a few extra bucks, or just for the sake of doing it. But only those who are doing it constantly, twice a week, every week (that’s the maximum) for a long period of time will develop a scar.
