A broad social safety net makes a huge difference. It’s not just housing it’s socialized medicine, paid family leave, good transit, free high quality education, solving fewer problems with police and more with social support programs and social workers, free meal programs for adults and children in schools, libraries, and a variety of other programs that help ensure people don’t fall through the cracks here or there. How many people in the US are teetering on the edge of homelessness due to medical debt, and what happens if their partner is in an accident and they lose shared income for rent? Situations like this don’t have a single solution it’s a system of solutions.

Ship them somewhere else, then print a banner saying, "mission accomplished."

It worked at a state level for years, with certain states bussing their homeless to other states. And recently, the USA has been building up the capability to do the same thing on an international scale.

That's the "solution" we are going to be throwing money at. Ship them to labor camps propped up by horrible regimes.

Many experiments have shown that when you take away people's concerns about money for housing and food, that frees up energy and attention to do other things.

Like the famous experiment in Finland where homeless people were given cash with no strings attached and most were able to rise out of their despair. The healthcare professionals could then focus their energy on the harder cases. It also saved a bunch of money in the process.
