This article is awesome in its ignorance and "splaining".
I lived for years homeless, and I fear little to nothing in this article describes neither the cause nor the cure for the millions of fellow humans having to live like animals. If Trump or George W. Bush were born poor and had to struggle with major trauma, they would be just as at risk as any other Americans. 
Jobs exported, catering to the investor class, Reagan's destruction of subsidized housing, insane wars, insane housing costs, the tossing out of the lost who make mistakes and end in prison...
You want to end homelessness, then bring back the draft, institute a guaranteed jobs program, triple the money available for public housing, end tax loopholes that let Richie Rich and his Trumpian friends do things like make all pay for their losses...Homelessness is about joblessness and trauma and the feeling that one is abandoned by one's family and country. Teach America to care first.
