A word on that from one of my favorite lectures for first-year students. The Red Cross issued its
call for blood donations while it was still thought there would be many, many victims who survived. Hospitals throughout the area were standing by for mass emergency admissions; off-duty medical personnel had been called in. Almost nobody showed up at the hospitals. Apart from the first responders, there were almost no injuries to be treated.
Everywhere people queued to give blood. It was a way that someone in Omaha or Tucson could do their bit to help. Often, it was all that they could do. The volume of blood donations was far beyond what could have been used even if there had been many survivors. Some of the donated blood was indeed thrown away, but some of it was used elsewhere and some of it was processed and stored.
I don't think
any of it was wasted. It was very important to let people offer their help. It turned out to be like some of the donation drives during World War II. For example, people were asked to store bacon grease and turn it in, with the supposition being that it would be used to lubricate artillery. That hardly ever happened, and it was known in advance that it would not happen, but it offered civilians a way to be a part of the war effort. The disappearance of color from margarine was similar, in that it was a symbol of a nation sacrificing for its troops and its survival. It is possible that gas rationing was also just a symbolic act.
Another way that people helped was to come to NY. A church band arrived from (I believe) Atlanta and ended up leading a parade every day for a couple of weeks. The streets were packed to cheer those going into the pit. St. Paul's Chapel, the refuge for first responders, was staffed by volunteers who would come for a week from all over the country and then go back home. While there was need, there was always someone there. St. Paul's still serves as a refuge for those who have found the site hard to bear. Alcoholics Anonymous set up 24/7 meetings on two sides of the pit, because crossing it took so much time and effort; those meetings were heavily attended by people who were so hurt by what they were seeing that they feared they would turn to drink. As it turned out, many of them did in the aftermath.
This is how societies respond to crises. I think of it as being like
Battle at Kruger. We can band together when we need to do so.
