So, instead of finding ways to help the less fortunate and reduce homelessness, it was seen as better to find ways to get the problem to go elsewhere. As if turning off the WiFi means the homelessness problem will just disappear too.
And regardless, San Francisco's homeless problem won't go away by ignoring it or pretending to. Makes more sense for the city and area to deal with it, by coming up with more effective and humane solutions. To not do so, creates a worldwide bad look and increases the embarrassment. Various people (or groups) are already making fun of the US by constantly reporting on and shooting videos of its huge numbers of homeless, to push back on the bragging, bravado, and hypocrisy.
SF is incapable of digging itself out of that hole. Clearly it's not a problem of insufficient spend, and the local politics will not allow for the necessary level of action, so this will continue in perpetuity until there is outside intervention.
"We need to humane harder" is clearly not working. It feels good in the short term, but 10 years later things only get worse and we're scratching our heads wondering why nothing is improving.
