Though SF seems to have problems that Silicon Valley (defined as the area from Sand Hill to downtown San Jose) doesn't have. Mountain View, for example, has a big homelessness problem, but it doesn't really have a huge crime problem. The typical homeless family (and it's families in MTV, vs. drug addicts in SF) lives in an RV, has a single working parent, keeps to themselves, and does their best to send their kids to schools. SF schools are some of the worst in the nation, while Palo Alto schools are some of the best. San Mateo cops actually arrest people. All these places have a greater tech concentration, greater average incomes, and greater income disparity than SF, and geographically they're located just 50 miles south.

I think the problems with SF are largely cultural and political rather than technological or economic, though the economic issues are exacerbating it. It's an "anything goes" city and has been for 150+ years. The city values your ability to express yourself in any way you please, and that includes both healthy forms like street fairs, neighborhood scavenger hunts, or Bring Your Own Big Wheel, and less-healthy forms like being able to shit on the sidewalk when you please or stab someone who looks at you funny. And that filters down to the voting preferences of the electorate. You get what you ask for.

The South Bay has all the same problems of tech dominance, income inequality, insane housing prices, etc, but the cultural orientation is very different. People in the South Bay are generally there to work hard and build a better life for themselves and their descendants. Their time-orientation is much more long-term than SF culture. And that applies across the income spectrum - even poor, Hispanic, immigrant day-workers will do their best to make sure their kids do their homework. The type of tech industry that spills out of this also reflects this cultural orientation, with the South Bay doing much more foundational engineering research and SF being more focused on how to apply technical breakthroughs from 50 miles south in new and crazy ways.
