Being able to be an active member of a society has costs associated and without the ability to at least cover for them you will be stuck as a social outcast, because you will already be considered a lesser of a candidate while job seeking. Proper dressing, hygene, transportation, meals, able to crash under a roof with basic access (electricity, modern communication tools)...

Insensitive people seem to give all these costs for granted. If you don't have these stuff you are literally stuck, with a retroactive and compounding effect.
