Read somewhere that SF spends roughly 50k$-80k$ per homeless person per year.
Taxing more doesn't solve a massively inefficient system at it's core. Just like US education, we spend more than any country on earth, why is it still bad?
Answering that question with a "if only we had more money" is a really poor argument. The CA tax fundamentals are bad, pooring more cash onto the fire will not fix that.
