The perfect storm. Landlords that are not practicing responsible policies, i.e., maintaining a “fair and reasonable” profit margin and using the more greedy what the market will bear policy. Run that lack of maintaining a fair profit with abandoned social responsibility up against the homeless who may not be particularly flexible nor motivated and you have the perfect storm.  (You don’t see many “hispanic or asian” individuals, the two largest groups of illegal’s  according to statistics, among the homeless). Why is it that illegal’s who have little or no support on arrival seem to find a way to survive? ...., and many resident citizens are unable to. Does that mean the homeless are drug  and or alcohol addicted, mentally ill or unmotivated and inflexible?
The solution will need to be beyond housing.
