My question wasn't intended to be confrontational toward you. It was inteneded to be informational to me.  I see that in my absence Lynn has presented you with some information. I hope you take it under consideration.
The reason I asked about your experience with homelessness is because you seem to be taking this personally. This is an ongoing crisis that is expanding in direct proportion to technological progress. Asking me to knock that chip off your shoulder with some kind of proof that one particular method of addressing the issue is superior to another isn't very productive. But giving up a cigerette habit isn't prevention.
Those of us who are old enough have heard it all before. The corporate lobbyist who petitioned the government to allow the MNCs to ship our jobs to blahblahblah.  The CEOs did it. The government did it.  
But aren't WE the government? We are well beyond the point of placing blame.
If housing the homeless is the least we can do, let's do it.
Shelter for all.
