YOUR source said only 1/3 have a current substance abuse issue. And my source said that 53% of homeless folks in shelters have jobs while 40% of unsheltered folks have jobs. Most homeless folks start out using shelters and then transition to living on the street as they loss hope and ergo lose employment as their Material Conditions worsen. I am done arguing with your surface level understanding of a complex crisis. I pray you and yours never experience the crushing hopelessness that is living on the street and not knowing where you will rest your head.
