So is the Pope, who also does not set policy in the municipality of San Francisco. To reply to your question: the mayor and city council (which is a group of humans, a species which is famously given to disagreement between individual members) of San Francisco have some power to improve the situation, but even they have precious few examples of cities to have attracted and generated tremendous wealth without also having tremendous poverty and depravity, frequently sited literally across the street from said wealth. What US cities have done so humanely?
