3 hours of my life are way more worth than that.
Sure, some people make more than 22 dollars an hour. They have promotions that are here and there, I believe the current one is 5 donations and $300 which would come to around $40 per donation. Then there is a possibility that you will have to report your earnings during tax season... which would either increase the amount you owe or it would decrease the amount you are receiving. At the same time someone can argue that they make more than $22 an hour, but they are only allowed to work 40 hours a week and they would like a little more income.... For myself, I am more worried about the health side effects. It is hard for me to reason that having a needle shoved in your arm and taking out vital fluid that one needs for survival is not detrimental to ones own health.
