I take deep interest in this subject, due to personal experience. As a working mom, I was homeless more than once and very close to homelessness multiple times. There were no drugs or alcohol involved, just rent raised, child support not paid, too expensive or the lack of childcare, enrolled in nursing school full time, or not enough working hours available. And I love the "If you can't afford them, don't have children" comments. I could afford the kids when they were born, but circumstances changed later due to factors beyond my control.
Many homeless are on the street, in tents, in vehicles or doubling up with family members and others for multiple reasons. At my worst, I was in a low rent, extended stay motel, but I was a hairsbreath from living in a tent. I consider myself lucky that I never had to live on the sidewalk. I got out of those situations by luck and hard work. The luck part is what many homeless folk have never gotten.
It's easy to demonize the homeless and issue blanket statements like "get them off the sidewalks" or "force them into shelters", "put 'em in jail, a work (concentration) camp or the poorhouse (though those no longer exist)" or "run them out of town". It's easy enough to be intolerant of the poor. I was on food stamps and Medicaid and WIC for about a year and the withering glances and rude treatment from strangers who had no knowledge of my situation were discouraging and hurt a lot. But regardless of what punishments the non-homeless want to impose, we have this pesky little impediment called the "Bill of Rights". We've managed to suspend that in multiple cases with American Indians, the Japanese during WW2 and now the current camp situation on the Southern border. We can't do that to the homeless-yet. God bless the ACLU!
Given the fact that the powers that be, of all political persuasions, are not willing fix the growing income inequality, the shrinking affordable housing stocks, a pitiful social service net, enough drug and alcohol treatment facilities and a myriad of other factors, the homeless situation is going to get worse. Did you realize that once a person is evicted from housing for any reason, almost universally, they will not be be able to rent again for seven years until it's off their credit record? And once someone has a criminal record, they will often never be able to get into any Fair Housing units-forever? Let's criminalize homelessness even more!
As far as the large percentage of the homeless addicted to drugs or alcohol? If I were living that way, I think I would want to be impaired enough to be able to tolerate the hopeless conditions on the streets. If you didn't have chemical impairments to start with, it will occur, given enough time on the streets. And the "Get a job!" prescription? Good luck with that when your clothes are dirty, you smell from no showers and you can't provide any address to a potential employer. Who wants to go to a shelter with crazies, the possibility of assault, bed bugs, scabies and poor treatment? Or, if you live in your car and you want safe parking, it only comes with the proviso that you go into the system and have to split up with your pets, significant other, your kids? Or if you go into a shelter, there's a good chance that you will have to give up your few possessions or even your car. No, the system is there to break the participants.
Many people refuse to consider even providing bathroom or handwashing facilities under the belief "if you provide services, like feeding pidgeons, more homeless will come for the luxurious services the homeless receive". Maybe when, that in addition to Hep A, TB, typhus, bed bugs, scabies, rat infestations, that when the Plague starts happening outside the homeless community, the idea of fixing at least part of this dysfunctional system might be considered. Most Americans are only a few missed paychecks away from homelessness. But rather than contemplating that, refusing to think of that possibility and looking down at the homeless is a better solution.
But I think that it's likely the suspension of the civil rights for the homeless will happen before meaningful change will occur. God forbid that we have UBI (Universal Basic Income) or Housing First should be adopted. Bootstraps only!
