Isn’t that a given?
A common framing of San Francisco's "homeless problem" might be called the magnet theory.
The city has allocated $165 million to homeless services. Over time, it has succeeded in offering 6,355 permanent supportive housing units to the formerly homeless. Nevertheless, the number of homeless people accounted for on the streets has remained stubbornly flat. The city estimates there are about 7,350 homeless people now living in San Francisco.
Since the city has invested so much with such disappointing results, the story goes, there can only be one explanation: Offering robust services has drawn homeless people from elsewhere, like a magnet. By demonstrating kindness, the city has unwittingly converted itself into a Mecca for the homeless, spoiling an otherwise lovely place for all the hardworking, law-abiding citizens who contribute and pay taxes.
and lastly I love the line.........In 2004, city officials and community advocates released a 10-Year Plan to Abolish Chronic Homelessness.
