Not sure why you're being down voted, this is the most honest statement about so called "homelessness" in the united states. It is affordable housing advocates essentially leveraging the mentally ill while completely ignoring their plight.
Almost all people you see on the streets end up there after burning all bridges in their personal lives because of their illness. You may not be aware of this but there are in fact a lot of options in existence for housing such people, it doesn't work because they are ill and without treatment (forceful), it is hopeless trying to help them.
