The poor are usually the mentally insane. They are all over the place here. The system rejects their disability payments and they get kicked out for being so strange and sometimes dangerous. They end up on the streets and need our help, since the gov doesn't take care of them. They fall into a viscous cycle where they have no access to medication. Which only perpetuates their homelessness.
"Their needs are often ignored until an outburst marks them a danger to themselves or others, when they may be involuntarily hospitalized and then rapidly kicked back to the street. (Roughly
30 percent of the state's unhoused residents suffer from severe mental illness.)"
