Just like addicts, homeless people are an industry. It's actually much cheaper to house people than it is to have all the services needed to keep people house-less when you add in the costs of shelters, free meal programs, mental health services, jail costs, etc etc etc. Salt Lake City has managed to house like 95% or more of their house-less, so it is possible but many don't understand or care enough to ask that it be handled. Especially with all these republicans in office, actually after this new tax plan, it's definitely going to get worse. I live in a city that is totally swamped with people on the streets (Portland, Oregon) and we are headed into winter. It's so heartbreaking to me. Just a couple nights ago I decided to drag out two quilts and a couple pillows, some gloves, and $10 to the woman who was sleeping just outside my window. I wanted to bring her in, but I know that's not a wise decision as a single female, although I feel it would've been fine.

I'd rather then get to the root of the problem rather than just come up with a temporary solution

This is a charter bus, and usually charter buses do have a small lavatory (similar to those on airplanes). So I expect that there is a tiny toilet and sink in the bus.

You don't know that for sure. There's nothing in the article that says they were influenced by a tour bus in Vietnam. They may not even know that it exists. I know that I've done things when I was younger that I though no one had done before but then I would find an article that shows the exact same thing. The point of this story is that THEY did something about homelessness.
