You asked me to compare my life to any human in 1973. I chose someone like me. Same identity, same geographic location, different time. Less than 5 years after the assassination of MLK and the Stonewall riots, that person would have been significantly more at risk than me of depression, destitution, or death from deficits in access to basic rights and resources - including, for all practical purposes, indoor plumbing (absent from my ancestral homestead in North Carolina), refrigeration (same), and a functional health department (same, particularly for gay men) - because of their race and sexuality. Nothing coming out of San Francisco office towers other than Harvey Milk was involved in changing those circumstances between then and now. I know this because I actually received an education in the humanities (which, informally, included working with Chinese and Indian legal professionals on a day-to-day basis). Did you?
As for the gadgets which you alluded to as contemporary society's savior just a few replies ago, I tend to attribute their existence to the basic research and, yes, cheap microcontrollers that made them possible, rather than the glorified middlemen who repackaged them as high-margin luxuries and sold them with spyware.

Also, like a concerned and informed adult, but yes.
>Exactly how much more should they be spending,
However much it would cost to house them permanently (and reduce housing insecurity in general), bounded by tax revenues, of course.
>and why would that change anything?
Well, generally-speaking, when a homeless person has housing, they cease to be homeless.
>Let's make this simpler for you.
I'd like you to stop projecting your own insecurities on me.
