> Not sure if you have lived near homeless encampments before. If you know you know.
I'm happy to put it all out there so people can judge where I'm coming from.
I'm not an expert on homelessness, either in a scientific sense or a first-hand one. I have a few long-term friendships with people who have at various points been homeless for a year or more (some traveling, some local to an area). For a couple years, I worked near a few hotspots for where homeless people would gather during the day and/or sleep at night in the downtown of a relatively small city. In college, I often had neighborly chats with the local homeless people who regularly went through the dumpsters in my apartment complex's parking lot. We'd chat whenever we met while I walked out there to take out the trash or let my dog go potty. Shortly after I graduated, some friends (now moved away, employed, and safely housed up!) who were homeless (then as well as when I first met them) moved in with me for a few months when the weather around us was utterly brutal and physically dangerous for them. When it feels safe (and I'm not on my way to appointment), which is pretty often, I stick around to chat a bit when a stranger approaches me to beg or vent about their life or meet my dog or whatever, whether they seem likely to be homeless or not.
I have seen people violently raving to themselves or at passersby, and I have seen people fight viciously over spaces in which to sleep or beg. I've conversed with people who seemed very lucid and insightful in some ways and paranoid or mentally disorganized in others. I have nervously avoided some people who were so agitated and incoherent that it made me feel unsafe. But admittedly, I have not ever lived in a huge city which has truly massive encampments of desperate people.
Over the years, I have talked in depth with people, including presently and formerly homeless people, about housing, employment, physical health, mental health, capitalism, familial rejection/abandonment, drug addiction, etc., and how those things relate to homelessness.
Personally, I think homelessness is a problem that requires a multifaceted approach to make people physically and financially secure, and to embed them in meaningful personal and professional supporting relationships in their communities. I think that approaches to addressing homelessness falling under the broad banner of 'housing first' are humane, scientific, and workable. And to me, access to housing as a public good is indeed way more important than promoting individual ownership of single-family homes (fwiw, like you, I'm a renter who'd rather not be).
But my main point in that remark you're replying to is that it's useless and incredibly tone-deaf to scold someone who is currently struggling with that level of hardship and societal rejection/abandonment for not buying into the prevailing political system, or for having a perspective in which the important similarities between the two parties are more salient than their differences.
