Every major city, and even most minor ones, have resources to help homeless people, if they WANT that help. The problem is that the homeless don't want to abide by the rules of these shelters - no drugs, no alcohol, no cohabitation with a sexual partner, no criminal activity, etc. - and therefore, of their OWN volition, can't stay there. In other words, they make the conscious choice to stay on the streets.
I've been tangentially involved with enough charity shelter organizations to know what the reality is. Drugs is the main problem. And there are loads of programs to help these people get off drugs, IF they want it.
Another good example are those who had businesses and lost them due to endless lock downs & closure of their business due to government responses with regards to the plandemic.
I'm not arguing with you, I am just saying, you cannot paint the situation with a broad brush. While a vast majority are what you say are the homeless, but not every one.
In many locations, they are trying to force hotel & motel owners make their empty rooms available to house the homeless, for a fair market rate. I seriously doubt that fair market rate, will be either fair or even close to market rates. This will end up causing even more homelessness and inflation keeps making more & more people become homeless.
