That's kind of a silly thing to say given that the government of SF spends hundreds of millions of dollars on the homeless a year.
Are there further details/good articles you would be able to provide?
You can see the budget at [2]. Most of the budget goes to Supportive Housing, ie, paying for housing for people to keep them off the street.

So either: they got a ridiculous amount of homeless people, or they got a ridiculous hole in their wallet, or the city doesn't actually spend 100s of millions on the homeless.
