I worked in homelessness in a large city during the late 90s and early noughties. (Labour) The numbers of street homeless were way lower than now - and we had a huge range of options and support services. For starters, there were hostels for a range of people - young people, older people, women only, wet houses, dry houses, dog friendly and so so. There were supported housing options - again varied - so people could be helped to move on.
Of course, for various complex reasons, some people did not leave the streets. They would be visited twice a day for food/hot drinks /fags/companionship. Even those living in the woods just outside the city. A CPN and mental health Social worker would go out with the workers a few times a week to get to know people. There was one woman who didn’t want to move into a hostel but opted for us to collect her every week or so so she could have a bath, and then we’d return her to her spot.
Many friends still work in the same area in homelessness. Services are decimated and numbers are through the roof. Hostels are understaffed and many feel unsafe for residents and for staff. It’s bloody awful.
