It is estimated that 20–25% of homeless people, compared with 6% of the non-homeless, have severe mental illness.
Others estimate that up to one-third of the homeless suffer from mental illness.
Are you implying America discriminates against the mentally ill?
The answer is yes.
I think a lot of people have mental illness but manage to live thanks to aids, healthcare, affordable housing, and so on. Because these structures are missing in America, these people end up in the street and their mental illness is the focus of the blame.
