Yeah I think the problem with viability is also, some 'homeless' in SF are actually housed, they're just poor n scruffy.

Last three years though I'm seeing people that are homeless and not scruffy. Friend of a friend was living in a panel truck with her 6 year old daughter for a year.

My solution is fairly simple, force the tech companies to direct their firehose of free cash somewhere else like Detroit or Albuquerque.
