Most people experiencing homelessness are approached repeatedly by workers hoping to get them into programs that will provide them work, housing, mental healthcare.
There's a lot of complexity, like people who appear homeless but do have a place to sleep, but appear mentally ill.
For the most part, people in these situations are not looking for work or housing.
So what, if you lose your job, you can just sleep on the street and employers will line up to hire you? That sounds ridiculous.
