Places with good weather have huge visible homeless populations. (I have traveled all over the United States, and have been to all fifty states. AFTER EDIT: I have been in, and have lived in, gritty "skid row" neighborhoods of large United States cities, and have lived in Los Angeles.) Places with lousy weather, like the place where I grew up and now live, certainly have people who are "homeless" in the sense of not having a secure legal right to occupy a particular place at their own discretion, but most people with that lack of legal right to choose their living circumstances are indoors during cold winter nights. There is much provision of emergency shelter in the United States, by both governmental organizations and private charities. There are also both federal and state programs for providing free or heavily subsidized leaseholds for housing to poor families, and private charities that build single-family homes for poor families. People are more visibly out on the street in the United States mostly on a regional or seasonal basis.
Since quite a few of the comments here mention Europe, my question (as someone who has never been to any part of Europe) is where do people live in Europe if they have no personal funds to buy or rent housing? Do they live in housing operated by some unit of government, or where?
All of the above said, yes, I am not sure that United States social policy is a model for anywhere, and perhaps hackers working on social policy here would be helpful. There are already enough empty housing units in the United States to house everyone who needs a house. The tough policy issues are in allocating people to houses (or houses to people) and looking out for other aspects of everyone's welfare.
