Why homeless when there are plenty of jobs?? It must be the "homeless" are incapable as in disabled to be employed due to chronic mental illness. Addiction is treatable for those interested...chronic mental illness can only be managed and that reqires a comprehensive plan. Yes, the State has an obligation to those that are "ill"! 
Sure hope that more mental health facilities are made available...as a good portion of the homeless campers are in need. Unfortunateky many feel at home in these camps while some are being taken advantage of. Come on Oregon and local communities, step up the care for the mentally ill and limit the vagrancy and loitering on public land...they are capable of work and should be doing so, not free loading on the backs of others. Try California...wanting to be a Sanctuary State....likely they will take in "homeless" campers - no need to work, no questions asked.
