I can't speak for SF's homeless but here in New England it seems the drastic increase in homeless has not really been from gentrification but rather the opioid problem. The disturbing thing is (and yes its anecdotal based on Waltham, MA) it seems to be an increase in younger-not-that-poor-to-start off with people. I don't want to go back to the ole 80's DARE drug war but I have to wonder if opioid abuse was even mitigated a little or rehab improved what kind of impact that might have on the homeless population. I guess what do people think is fueling SF's homeless population increase?
