If you read that article it talks about how some of that money is spent on prevention so it's a bit unfair to just use existing homeless as the denominator- it's still an obscene amount of money per person. So saying it's "totally incorrect" is a bit of a stretch.

San Francisco absolutely has a Homeless industrial complex that isn't trying to solve the problem but just keep their cash flowing.

The article calculates that the actual amount spent per "visible homeless person" was ~$3800 per year in 2018. The majority was spent on prevention.

It seems pretty fair to say that being off by 10x is "totally incorrect".

If you use the term "Homeless industrial complex" then it is immediately obvious that you have no idea what you are talking about.

You’re linking to an article from mid 2018, before SF passed the largest tax in the city’s history: 2018 Prop C, a gross receipts tax for homeless services expected to raise another $300M. Several other additional tax measures were also passed since then to raise funds for homeless services.

These do not make fifty thousand opex per homeless person per year or anything around that. Both before and onwards, much is capex to build out.
