Well, I guess I'm not surprised that "We're Number 1!"
I have big problems with the structure of our city/county government. My essential criticism is that as the 2nd smallest county in the country ... there is a smaller one in Hawaii ... we're "overgoverned," with 11 members of our Board of Supervisors.
I think that every other county, in California, has a 5 member board. Many of those much larger counties have to deal with; heavy industry, concerns with massive agriculture and ranching, coordination among large cities, small towns and unincorporated areas.
Breaking up ONE city, that is only 49 square miles, into 11 little fiefdoms, with representatives that focus on self-interest is insane. I have long advocated for going back to at-large county supervisors, and greatly reducing their number.
Along with the status as a small, single-city county, we are 2nd only to New York City in density.
Save for my high school years, when the family moved just over the city/county line, into Daly City (San Mateo County), and 4 years of school in Oregon, I've never lived anyplace else. So, I can't speak to the challenges of the other cities on the list.
Homelessness is a serious problem in many major cities. And, it's legendary, here. The relatively temperate climate of the west coast, my be an attraction. The same probably holds true for the general liberal trend toward trying to treat the problem with a measure of humanity. I don't have answers, on that front. If I did, I'd campaign for office.
I'd be curious to hear from residents of other "top ten" cities.
