It helps to realize that there are two distinct groups of homeless. One is just people who experienced financial hardship because capitalism and just need some help to get back on their feet.

The other is a group that is chronically homeless because they are severely mentally ill and don’t want to take their meds (which fair, the side effects of antipsychotics blow), addicts who have no desire to get sober yet, or a combo of the two (self medicating their mental illness). Some of these people are literally feral (skid row in LA is a good example).

Even though they are a minority of homeless, those people are what makes homelessness such a difficult issue to tackle. At some point you’d have to involuntarily commit them and force them to get help and stay compliant. It’s not just an issue of lack of affordable housing.
