I don&#x27;t think that&#x27;s a tragedy of the commons. There&#x27;s no rational self-interest in people who would rather walk past human misery every day than put a extra couple of dollars towards alleviating it. As you say, proper, civilized mental health funding could go a long way towards fixing this problem; even just funding for public restrooms with full-time attendants would help; but we can&#x27;t get it. It&#x27;s hard to put that down to anything other than self-absorbed callousness.
