It could not be solution because homelessness is not a structural problem but a facet of a deeper one. From what I have read the US has 2 huge social problems right now - the unemployment and the war on drugs. Until the employment moves of the death spiral it is in right now you will always have fresh supply of homeless people.
Having both studied it and lived it, my best understanding is that homelessness is generally rooted in having too many intractable problems combined with too few resources to meet them. No one thing causes it but, certainly, structural issues can change the tipping point at which available resources fail to be sufficient to one's needs. So while changing the housing stock won't solve it, it can help reduce the problem.
I am not sure that I got understood - I meant that you should not give the homeless a house. You should give the homeless a house and a job if you want the issue solved (or better access to healthcare, or whatever was the stuff that put him in the downward spiral). I absolutely support providing roofs above the heads on the vulnerable people. I just think it don't goes nearly far enough.
No, it does not go nearly far enough. Most homeless people have either medical or mental health issues which are barriers to making their lives work conventionally. Supportive housing sometimes works where just access to housing per se may not. This is a much more complicated problem than just 'jobs and housing' (availability) but those things both help.
