I used to commute to SF for a year and it was shocking to me how the home to one of the wealthiest companies and residents are overwhelmed with homelessness and crimes.

The scene of downtown was something out of a dystopian movie where you see wealthy people walking by a drug addict with needles on the ground and yet everyone appears to conform that this is the norm

I'm definitely oversimplifying the problem here but intuitively shouldn't a city with high income have more money to spend on infrastructure?

Where are the taxpayers money spent on?
