I don't want to rip on GP, I think they were more sharing a quirk than calling to action. But I have a mental model of "shared cost" that I wish more people had: if the cost for me to grin an bear it is less than the sum of the costs of everyone else changing, it's probably not worth changing. Obviously there are extreme nonlinearities involved in these costs. Very bad things for a few individuals are worth lots of small changes for a majority.
