This is only the United States. You are talking about problems in the United States and comparing them to other cities in the United States most of which have the same problem. Its worth mentioning also that San Francisco city proper is a tiny area and not remotely reflective of the Bay Area. It has 800K people in an area with almost 8 million people. For comparison's sake. Seoul, South Korea has 40K people per square mile (total population of 8 million people). That is the entire city. Overcrowded San Francisco city proper has 17K people per square mile and it is by far the most dense part of the Bay Area.
