The chronically homeless I encounter in SF are primarily (not all) 1. Addicted to drugs 2. Suffering from psychiatric issues. No amount of affordable housing is going to fix that. No amount of training, educational assistance, universal income etc will fix that. They are not in any condition to work or hold a job or do personal health maintenance. Give them shelter and they wonder off.

Affordable housing is affecting the middle class rather severely in that larger portions of the middle class incomes are being spent on housing. These are people that are not homeless. These are people often in trades or hourly labor. Some will become homeless with any disruption of income. Fl has done some things to help with that. "...in recent years Florida communities have embraced evidence-based best practices such as Housing First, collaborative case management, and rapid rehousing."{1}

Mathematically speaking there is no reason why CA cannot have %50 of the homeless. CA could have %100 of the homeless if no other states have homeless. It is not related to CA population relative to the rest of the country.

The problem IMHO is that results matter more than good intentions. Many of CAs programs mean well but are either not executed well or simply do not work. The proponents continue to promote them and receive money for them despite their inability to get results. That is were all the money goes.
