That's just false. Mental issues and drugs certainly are responsible for a decent portion of the homeless, but the lack of affordable housing is a massive issue for millions of people across the country, many of whom become homeless because they cannot find an affordable place to live. The mentally ill homeless man sleeping on the sidewalk and causing a disturbance is the most visible, but for everyone of them there is someone who is sleeping in their car or on a friend's couch or in a tent. And for every person that is homeless now there are a dozen other people who are living paycheck-to-paycheck, one illness, car accident or other unforeseen expense away from being homeless. The fact is that homelessness is as much an economic problem - one that is becoming worse every year - as it is a problem of mental health and drug addiction. Our social safety net has failed for the poorest Americans and the situation continues to worsen as we whittle away at what remains of that net and more and more Americans slide deeper into poverty.
