I don’t care. Have you ever been in need of a blood transfusion and been told by a nurse that they don’t have one available in your blood type? I have. I almost died in 2012 from blood loss. I am lucky to be alive today. If some other O- donor would have just been there to help, or had donated a week or so before that day, it would have been an easier recovery. I donate because I know someone in a hospital needs my blood donation to survive. A human life is worth more than the few dollars the blood bank actually makes from my donation. Most of the money from the blood transfusion cost goes towards the medical procedure, the actual process of transporting it, and testing the blood to make sure it’s safe. The blood bank needs to keep operating. It’s not owned by some billionaire. I hope you never need a blood transfusion. It will make you change your priorities if you do.
