From this morning's WSJ:

The number of homeless people in California grew about 50% between 2014 and 2022. The state, which accounts for 12% of the U.S. population, has about half of the nation’s unsheltered homeless, an estimated 115,000 people, according to federal and state data last year. It also has among the highest average rent and median home prices in the U.S.

California spent a record $17 billion combating homelessness in the past four fiscal years. For the state budget year starting in July, Gov. Gavin Newsom has proposed another $3.7 billion.

Voters in Los Angeles and San Francisco, which have some of the largest homeless populations in California, were unhappy enough about it to approve taxes costing them billions of dollars to fund anti-homelessness programs and housing in recent years. So far, cost overruns and delays have left little to show for the money.
I'm sad to say it seems they need to find another approach
