This is very true. Sadly there is zero chance of finding a politically-palatable solution for this one in California.

What is the non-politically-palatable solution?

Build subsidized housing for people who need it. Time and time again experience has shown that to be the cheapest solution. But many Americans who never grew past toddlerhood find that unacceptable because it means someone else is getting something they aren't.

I guess you'd have to be at least in grade school to think this subsidized housing should be built in the most expensive areas of the country/world?

Lol. Yeah, and just keep building MORE free housing next year to give away as the Greyhounds keep rolling in. Of course, it's criminal to even suggest building it somewhere less expensive. Only the finest and most convenient locations will do! So, to afford the land and materials, and the armies of social workers, uhh, just raise payroll and property taxes?

Yes, exactly this. Additionally we have seen how many once beautiful cities and parks have turned into unsafe homeless camps because of government policy. If I buy a house with a nice backyard I can guarantee that it will be nice as long as I maintain it. I cannot guarantee that the local park will not turn into a needle strewn homeless camp sometime in the future when some politician changes something.

And people will be homeless in large numbers until enough housing is built for them, and the government is allowed to spend the $x to house them rather than the $(x * y) required to deal with all the effects them being homeless.
