I am no psychologist, but I know that psychological intervention requires followup.



By virtue of the transient nature it is hard to regularly offer this service framework to this population. This is not to discount the sterling work offered by voluntary agencies or individuals.



From the financial aspect, you are asking a person to devote time and

resources with no/minimal financial return. Some people dedicate their career

to this path; some a few sessions and many don't. It is a personal choice

that other folks may frown on, but the operative word is personal.



From the professional aspect, there is a question of referral and contact. Family doctors are a common point of referral as well as link up to provide service.

Most homeless folks don't have one.



I am uncertain as what you mean by high level psychologists. If you want to project an image of a professional working in some sort of deprived area by this

question then I have tried to provide a professional answer. I cannot escape the tinge or connotation that you want Frasier figures to be there at soup lines. There are many support workers who care passionately about providing a similar service, understand the needs and can relate to the people they help and come into contact on a near regular basis... is that not more appropriate?
